Log Message:
-----------
Fix an oversight in convert_EXISTS_sublink_to_join: we can't convert an
EXISTS that contains a WITH clause.  This would usually lead to a
"could not find CTE" error later in planning, because the WITH wouldn't
get processed at all.  Noted while playing with an example from Ken Marshall.
