[SPARK-12218] [SQL] [Backport-1.5] Fixed the Parquet's filter generation
rule when `Not` is included in Parquet filter pushdown
Added the test case that can cause data loss in the following scenario:
When applying the operator Not, the current generation rule for Parquet
filters simply applies `Not` to all the inclusive/underlying filters.
Note: will submit the fix after the test case failure.
