[SPARK-17838][SPARKR] Check named arguments for options and use formatted R friendly message from JVM exception message

## What changes were proposed in this pull request?

This PR proposes to
- improve the R-friendly error messages rather than raw JVM exception one.

  As `read.json`, `read.text`, `read.orc`, `read.parquet` and `read.jdbc` are executed in the same  path with `read.df`, and `write.json`, `write.text`, `write.orc`, `write.parquet` and `write.jdbc` shares the same path with `write.df`, it seems it is safe to call `handledCallJMethod` to handle
  JVM messages.
-  prevent `zero-length variable name` and prints the ignored options as an warning message.

**Before**

``` r
> read.json("path", a = 1, 2, 3, "a")
Error in env[[name]] <- value :
  zero-length variable name
```

``` r
> read.json("arbitrary_path")
Error in invokeJava(isStatic = FALSE, objId$id, methodName, ...) :
  org.apache.spark.sql.AnalysisException: Path does not exist: file:/...;
  at org.apache.spark.sql.execution.datasources.DataSource$$anonfun$12.apply(DataSource.scala:398)
  ...

> read.orc("arbitrary_path")
Error in invokeJava(isStatic = FALSE, objId$id, methodName, ...) :
  org.apache.spark.sql.AnalysisException: Path does not exist: file:/...;
  at org.apache.spark.sql.execution.datasources.DataSource$$anonfun$12.apply(DataSource.scala:398)
  ...

> read.text("arbitrary_path")
Error in invokeJava(isStatic = FALSE, objId$id, methodName, ...) :
  org.apache.spark.sql.AnalysisException: Path does not exist: file:/...;
  at org.apache.spark.sql.execution.datasources.DataSource$$anonfun$12.apply(DataSource.scala:398)
  ...

> read.parquet("arbitrary_path")
Error in invokeJava(isStatic = FALSE, objId$id, methodName, ...) :
  org.apache.spark.sql.AnalysisException: Path does not exist: file:/...;
  at org.apache.spark.sql.execution.datasources.DataSource$$anonfun$12.apply(DataSource.scala:398)
  ...
```

``` r
> write.json(df, "existing_path")
Error in invokeJava(isStatic = FALSE, objId$id, methodName, ...) :
  org.apache.spark.sql.AnalysisException: path file:/... already exists.;
  at org.apache.spark.sql.execution.datasources.InsertIntoHadoopFsRelationCommand.run(InsertIntoHadoopFsRelationCommand.scala:68)

> write.orc(df, "existing_path")
Error in invokeJava(isStatic = FALSE, objId$id, methodName, ...) :
  org.apache.spark.sql.AnalysisException: path file:/... already exists.;
  at org.apache.spark.sql.execution.datasources.InsertIntoHadoopFsRelationCommand.run(InsertIntoHadoopFsRelationCommand.scala:68)

> write.text(df, "existing_path")
Error in invokeJava(isStatic = FALSE, objId$id, methodName, ...) :
  org.apache.spark.sql.AnalysisException: path file:/... already exists.;
  at org.apache.spark.sql.execution.datasources.InsertIntoHadoopFsRelationCommand.run(InsertIntoHadoopFsRelationCommand.scala:68)

> write.parquet(df, "existing_path")
Error in invokeJava(isStatic = FALSE, objId$id, methodName, ...) :
  org.apache.spark.sql.AnalysisException: path file:/... already exists.;
  at org.apache.spark.sql.execution.datasources.InsertIntoHadoopFsRelationCommand.run(InsertIntoHadoopFsRelationCommand.scala:68)
```

**After**

``` r
read.json("arbitrary_path", a = 1, 2, 3, "a")
Unnamed arguments ignored: 2, 3, a.
```

``` r
> read.json("arbitrary_path")
Error in json : analysis error - Path does not exist: file:/...

> read.orc("arbitrary_path")
Error in orc : analysis error - Path does not exist: file:/...

> read.text("arbitrary_path")
Error in text : analysis error - Path does not exist: file:/...

> read.parquet("arbitrary_path")
Error in parquet : analysis error - Path does not exist: file:/...
```

``` r
> write.json(df, "existing_path")
Error in json : analysis error - path file:/... already exists.;

> write.orc(df, "existing_path")
Error in orc : analysis error - path file:/... already exists.;

> write.text(df, "existing_path")
Error in text : analysis error - path file:/... already exists.;

> write.parquet(df, "existing_path")
Error in parquet : analysis error - path file:/... already exists.;
```
## How was this patch tested?

Unit tests in `test_utils.R` and `test_sparkSQL.R`.
