IMPALA-8140: Fix use-after-poison in grouping aggregator

IMPALA-7333 changed the memory transfer semantics to move memory when
attaching it to the output batch instead of copying it. This caused a
use-after-poison when the cleaning up the hash tables during the call to
Close(). To fix this, we now clean up the hash table before closing the
output row stream.

Testing: added a test to aggregation.test
