    Don't force unicode strings for UUID coercion

    Change Ic6b6308fb1960ec40407e6efde30137b64543e72 attempts to
    fix difference between Python 2 and Python 3 values by switching
    from using str() to formatting into a unicode string (u"%s").

    This is equivalent to changing str() to unicode(), but that is
    not correct for expected default string types for Python 2.
    This requires either using six.text_type(), or just formatting
    into a string, without forcing unicode ("%s"), to be correct on
    either runtime.
