HPCC-8516 Fix problem with ROWS(RIGHT) in keyed denormalize

If the index used in a keyed denormalize(,group) contained a child dataset
then a reference to ROWS(RIGHT) would generate an internal error.  This is
because it was acccessing a deserialize dataet, but the dataset passed in
is serialized.
