Updating route_id updates AgencyAndId object and not the route's id.

[romainguefveneu]

Summary:

Updating route_id updates AgencyAndId object and not the route's id, leading to have the agency code postfixed to the new route id.

Steps to reproduce:

  @Test
  public void testUpdateRouteId() throws Exception {
    _factory.addModificationsFromString("{'op':'update', "
            + "'match':{'file':'routes.txt'}, "
            + "'update':{'route_id':'s/r/route/'}}");

    GtfsTransformStrategy transform = _transformer.getLastTransform();
    TransformContext context = new TransformContext();
    GtfsMutableRelationalDao dao = new GtfsRelationalDaoImpl();

    Route route = new Route();
    route.setId(new AgencyAndId("a0", "r0"));
    dao.saveEntity(route);

    transform.run(context, dao);

    assertEquals("route0", route.getId().getId());
  }

Expected behavior:

It should transforms r0 into route0

Observed behavior:

It transforms r0 into a0_route0
