 feat(py3): Convert unicode-only modules to str

 Modules that reference `unicode` but do *not* reference `str` can safely
 be converted to
 use `str` in a way that's closest to the way it should be done under
 Python 3 but that
 is still Python 2 compatible [per
 `python-future`](https://python-
 future.org/compatible_idioms.html?highlight=unicode#unicode).

 This change results in 4 additional tests passing under Python 3 that
 weren't before,
 one previous test error is now a failure, and more coverage in a few
 modules.  Here's
 the diff of the output from running all tests under Python 3 before these
 changes and
 after.  I've elided the irrelevant changes (time stamps, object ids,
 etc.):
