Fix parsing of qualified relation names in RETURNING. Given a qualified refname, refnameNamespaceItem() will search for a matching namespace item by relation OID, rather than by name. Commit 80feb727c8 broke this by adding additional namespace items for OLD and NEW in the RETURNING list, which have the same relation OID, causing ambiguity. Fix this by ignoring these in the search, which is correct since they don't match the qualified relation name, and so there is no real ambiguity.
