IMPALA-5788: Fix agg node crash when grouping by nondeterministic exprs
Fixed a bug where impala crashes during execution of an aggregation
query using nondeterministic grouping expressions. This happens when
it tries to rebuild a spilled partition that can fit in memory and rows
get re-hashed to a partition other than the spilled one due to the use
of nondeterministic expressions.
Testing:
Added a query test to verify successful execution.
