Aggregate expression with filter is incorrectly translated to Comet aggregate native aggregation expression

[viirya]

Describe the bug

Another one bug found while fixing test failures in #250.

Aggregate expression with filer is incorrectly translated to Comet aggregate native aggregation expression without filter now. It causes at least one query failure.

For example, in org.apache.spark.sql.SQLQueryTestSuite:

[info] - count.sql *** FAILED *** (3 seconds, 483 milliseconds)
[info]   count.sql
[info]   Expected "[1	1]", but got "[2	2]" Result did not match for query #7
[info]   SELECT count(DISTINCT 2), count(DISTINCT 3,2) (SQLQueryTestSuite.scala:495)
