[HOT-FIX] bypass hive test when parse logical plan to json

https://github.com/apache/spark/pull/10311 introduces some rare, non-deterministic flakiness for hive udf tests, see https://github.com/apache/spark/pull/10311#issuecomment-166548851

I can't reproduce it locally, and may need more time to investigate, a quick solution is: bypass hive tests for json serialization.

Closes #10430 from cloud-fan/hot-fix.
