usrloc - fix db_delete_ucontact_ruid

when the contact is deleted using db_delete_ucontact_ruid (default)
the uldb_attrs_delete is not called leaving the location_attrs with unwanted records

created uldb_attrs_delete_ruid to be called by db_delete_ucontact_ruid
redirected uldb_attrs_delete to uldb_attrs_delete_ruid when ul_db_ops_ruid == 1

(cherry picked from commit 09c5168)
