Small mistake in test_principal.py

[mickey06]

This

    def test_and_permissions_view(self):
            self.assertRaises(PermissionDenied, self.client.open, '/g')

should be

    def test_and_permissions_view(self):
            self.assertRaises(PermissionDenied, self.client.open, '/h')

As it stands /h is never tested.
