[SPARK-2523] [SQL] Hadoop table scan bug fixing (fix failing Jenkins maven test)

This PR tries to resolve the broken Jenkins maven test issue introduced by #1439. Now, we create a single query test to run both the setup work and the test query.

Author: Yin Huai <huai@cse.ohio-state.edu>

Closes #1669 from yhuai/SPARK-2523-fixTest and squashes the following commits:

358af1a [Yin Huai] Make partition_based_table_scan_with_different_serde run atomically.
