[ASTERIXDB-2796][RT] Fix IndexOutOfBoundsException in hash group-by

- user model changes: no
- storage format changes: no
- interface changes: no

Details:
IndexOutOfBoundsException happens in hash group-by when WITH
clause exists. The variables from the WITH clause get propagated
through the decor variables of the group-by. The number of output
keys are the sum of both the group-by keys and decor variables, but
the hash functions & comparators used are only for the group-by keys.

- pass only the aggregated keys to the comparators and hash functions.
