[SPARK-12177][TEST] Removed test to avoid compilation issue in scala …

…2.10

## What changes were proposed in this pull request?

The commented lines failed scala 2.10 build. This is because of change in behavior of case classes between 2.10 and 2.11. In scala 2.10, if companion object of a case class has explicitly defined apply(), then the implicit apply method is not generated. In scala 2.11 it is generated. Hence, the lines compile fine in 2.11 but not in 2.10.

This simply comments the tests to fix broken build. Correct solution is pending.
