Forbid SJE with result relation

The target relation for INSERT/UPDATE/DELETE/MERGE has a different behavior
than other relations in EvalPlanQual() and RETURNING clause.  This is why we
forbid target relation to be either source or target relation in SJE.
It's not clear if we could ever support this.
