Fix join condition lost after pull up sublink to join
After pulling up the sublink to join, the raw join condition may get
lost in the rewritten query, potentially leading to incorrect results.
Within the SubqueryToJoinWalker() function, we address this issue
by adding an 'else' branch to prevent the loss of join clauses and
keep them in their original positions.
