[NO ISSUE][COMP] Fix schema computation by UnionAll

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

Details:
- UnionAllOperator.recomputeSchema() is incorrect and might
  produce huge variable lists for nested UNION ALL operations.
  This can lead to out of memory during query compilation.
