* Data migration: Alter CharField to SlugField for 2 fields in CourseTeam model

I'm surprised this didn't cause an issue before but as far as I can
figure this should always be non-greedy.  I think it worked before
because the items we were looking for was previously the last item
in the list but that is no longer the case in python 3 because of
dictionary order changes.

* For all files, from __future__ import unicode_literals.
* Add @python_2_unicode_compatible to both models.
* Test six.string_type(obj) for both models.

Also, fix some new pylint warnings and improve model repr methods.
