[NO ISSUE][COMP] Fix outer join handling in some optimizer rules

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

Details:
- LoadRecordFieldsRule should not search for fields in the right
  branch of a left outer join
- ExtractCommonExpressionsRule should not perform common
  expression extraction if one expression is in the right branch of
  a left outer join and another expression is above the outer join
