Herman van Hovell 760c8d088d [SPARK-20329][SQL] Make timezone aware expression without timezone unresolved ... ## What changes were proposed in this pull request? A cast expression with a resolved time zone is not equal to a cast expression without a resolved time zone. The `ResolveAggregateFunction` assumed that these expression were the same, and would fail to resolve `HAVING` clauses which contain a `Cast` expression. This is in essence caused by the fact that a `TimeZoneAwareExpression` can be resolved without a set time zone. This PR fixes this, and makes a `TimeZoneAwareExpression` unresolved as long as it has no TimeZone set. ## How was this patch tested? Added a regression test to the `SQLQueryTestSuite.having` file.
