[SPARK-19022][TESTS] Fix tests dependent on OS due to different newline characters

## What changes were proposed in this pull request?

There are two tests failing on Windows due to the different newlines.

```
 - StreamingQueryProgress - prettyJson *** FAILED *** (0 milliseconds)
 "{
    "id" : "39788670-6722-48b7-a248-df6ba08722ac",
    "runId" : "422282f1-3b81-4b47-a15d-82dda7e69390",
    "name" : "myName",
    ...
  }" did not equal "{
    "id" : "39788670-6722-48b7-a248-df6ba08722ac",
    "runId" : "422282f1-3b81-4b47-a15d-82dda7e69390",
    "name" : "myName",
    ...
  }"
  ...
```

```
 - StreamingQueryStatus - prettyJson *** FAILED *** (0 milliseconds)
 "{
    "message" : "active",
    "isDataAvailable" : true,
    "isTriggerActive" : false
  }" did not equal "{
    "message" : "active",
    "isDataAvailable" : true,
    "isTriggerActive" : false
  }"
  ...
```

The reason is, `pretty` in `org.json4s.pretty` writes OS-dependent newlines but the string defined in the tests are `\n`. This ends up with test failures.

This PR proposes to compare these regardless of newline concerns.

## How was this patch tested?

Manually tested via AppVeyor.
