The bug: During planning, when generating an EmptySetNode for a query block (or a portion thereof) that contained relative table refs we still populated the corresponding collection-typed slots in the parent scan, ultimately hitting a sanity DCHECK in the BE. The fix: Since those collection-typed slots are never used, the corresponding parent scan should not materilaize them. When creating an EmptySetNode we mark the appropriate collection-typed slots as non-materialized.
