I pushed a change to the test removing some of the use cases. The usernames being tested are actual users. In this case, that user is not confirmed and the URL returned by the API is different than what we would expect (it is of the format /user/uid). We can test this as well but this test might break in the future when this user gets confirmed. So, let's remove it instead.
