ambiguous contractions

the following unit tests have a TODO, we don't have anything concrete planned to solve this and should start discussing it

       # TODO: Ambiguous with "he had"
       self.assertEqual(normalize("he'd"), "he would"
       # TODO: Ambiguous with "he has"
        self.assertEqual(normalize("he's"), "he is")
        # TODO: Ambiguous with "how would"
        self.assertEqual(normalize("how'd"), "how did")
        # TODO: Ambiguous with "how has" and "how does"
        self.assertEqual(normalize("how's"), "how is")
        # TODO: Ambiguous with "I had"
        self.assertEqual(normalize("I'd"), "I would")
