Fixed the test introduced in 2ca37af6 under Python 3.

        places = list(Place.objects.order_by('links__id'))

        def count_places(place):

            return len(filter(lambda p: p.id == place.id, places))

            return len([p for p in places if p.id == place.id])

        self.assertEqual(len(places), 2)

        self.assertEqual(count_places(p1), 1)
