BUG#833600: Wrong result with view + outer join + uncorrelated subquery (non-semijoin)

- The bug was caused by outer join being incorrectly converted into inner because of 
  invalid return values of Item_direct_view_ref::not_null_tables().
- Provided a correct Item_direct_view_ref::not_null_tables() function.
