Test uncovered return of rhyming_part()

[hugovk]

The last line of rhyming_part (refactored in https://github.com/aparrish/pronouncingpy/commit/452aca8e26d914389d067abad41755a9ee64ee24 from PR #4) isn't covered by tests.

def rhyming_part(phones):
    """Get the "rhyming part" of a string with CMUdict phones.

    "Rhyming part" here means everything from the vowel in the stressed
    syllable nearest the end of the word up to the end of the word.

    .. doctest::

        >>> import pronouncing
        >>> phones = pronouncing.phones_for_word("purple")
        >>> pronouncing.rhyming_part(phones)
        u'ER1 P AH0 L'

    :param phones: a string containing space-separated CMUdict phones
    :returns: a string with just the "rhyming part" of those phones
    """
    phones_list = phones.split()
    for i in range(len(phones_list) - 1, 0, -1):
        if phones_list[i][-1] in '12':
            return ' '.join(phones_list[i:])
    return phones

This is the case where CMUdict phone entries don't contain a zero or one, for example:

MCKREE  M AH0 K R IY0
MHM  AH0 M HH AH0 M
MURMANSK  M ER0 M AE0 N S K
NUSBAUM  N AH0 S B AW0 M

So let's test that. And coverage is back to 100%!
