[SPARK-15322][SQL][FOLLOW-UP] Update deprecated accumulator usage into accumulatorV2

## What changes were proposed in this pull request?

This PR corrects another case that uses deprecated `accumulableCollection` to use `listAccumulator`, which seems the previous PR missed.

Since `ArrayBuffer[InternalRow].asJava` is `java.util.List[InternalRow]`, it seems ok to replace the usage.

## How was this patch tested?

Related existing tests `InMemoryColumnarQuerySuite` and `CachedTableSuite`.
