Code review comment for lp:~sinzui/launchpad/person-merge-job-4

There is a False test and a True test in lib/lp/registry/tests/test_person.py:

    def test_no_merge_pending(self):
        # is_merge_pending returns False when this person is not the "from"
        # person of an active merge job.
        person = self.factory.makePerson()
        self.assertFalse(person.is_merge_pending)

    def test_is_merge_pending(self):
        # is_merge_pending returns True when this person is being merged with
        # another person in an active merge job.
        from_person = self.factory.makePerson()
        to_person = self.factory.makePerson()
        getUtility(IPersonSet).mergeAsync(from_person, to_person)
        self.assertTrue(from_person.is_merge_pending)
        self.assertFalse(to_person.is_merge_pending)
