MDEV-15555: select from DUAL where false yielding wrong result when in a IN
For the query having an IN subquery with no tables, we were converting the subquery with an expression between
the left part and the select list of the subquery . This can give incorrect results when we have a condition
in the subquery with a dual table (as this is treated as a no table).
The fix is that we don't do this conversion when we have conds in the subquery with a dual table.
