[SPARK-11103][SQL] Filter applied on Merged Parquet shema with new column
fail
When enabling mergedSchema and predicate filter, this fails since Parquet
filters are pushed down regardless of each schema of the splits (or rather
files).
This is related with Parquet issue
(https://issues.apache.org/jira/browse/PARQUET-389).
For now, it just simply disable predicate push down when using merged
schema in this PR.
