Clean up worker tests after Repository based right removal

Apparently I missed some things in !2347 (merged), at least in test_workers.py e.g.

    def test_workers_retrieve_repository(self):
        """
        A user can retrieve a worker by having contributor access on its repository
        """
        repo2 = Repository.objects.create(
            url="http://gitlab/repo2"
        )
        worker_2 = repo2.workers.create(name="Worker 2", slug="worker_2", type=self.worker_type_dla)
        repo2.memberships.create(user=self.user, level=Role.Contributor.value)
        self.client.force_login(self.user)

        with self.assertNumQueries(3):
            response = self.client.get(reverse("api:worker-retrieve", kwargs={"pk": str(worker_2.id)}))
            self.assertEqual(response.status_code, status.HTTP_200_OK)

        self.assertDictEqual(response.json(), {
            "id": str(worker_2.id),
            "repository_id": str(repo2.id),
            "name": "Worker 2",
            "description": "",
            "slug": "worker_2",
            "type": "dla",
            "archived": False,
        })

or

    @patch("arkindex.users.managers.BaseACLManager.filter_rights")
    def test_workers_retrieve_no_rights(self, filter_rights_mock):
        filter_rights_mock.side_effect = [
            Worker.objects.none(),
            Repository.objects.none(),
        ]
        self.client.force_login(self.user)

        with self.assertNumQueries(3):
            response = self.client.get(reverse("api:worker-retrieve", kwargs={"pk": str(self.worker_reco.id)}))
            self.assertEqual(response.status_code, status.HTTP_404_NOT_FOUND)

        self.assertEqual(response.json(), {"detail": "No Worker matches the given query."})

        self.assertListEqual(filter_rights_mock.call_args_list, [
            call(self.user, Worker, Role.Contributor.value),
            call(self.user, Repository, Role.Contributor.value),
        ])

which actually I don't understand passes ... I feel like it should be broken 😐
