[SPARK-2716][SQL] Don't check resolved for having filters.

For queries like `... HAVING COUNT(*) > 9` the expression is always resolved since it contains no attributes.  This was causing us to avoid doing the Having clause aggregation rewrite.

Closes #1640 from marmbrus/havingNoRef and squashes the following commits:
