ASTERIXDB-1727: Fix an issue with multiple aggregates in one group-by

 - Although the hash group-by hint is given, if multiple aggregate operators
   exist in the subplan of group-by, the physical operator of the given group-by
   should not be set as EXTERNAL_GROUP_BY since we don't support multiple aggregates
   in the external group by physical operator.
