    Change time faking for totp test

    This change moves the time mocking from using freezegun to
    using oslo.utils TimeFixture for the unit test
    test_with_passcode_in_previous_windows_extended, which was
    occasionally failing with 401 errors due to
    the totp creation time not properly be faked with
    4 extended windows.
