Django provided an old django.utils.encoding.force_unicode function,

which was only importable on Python 2.7. The "new" name (compatible with

Django 1.6) for this is force_text, which is importable on all Python

versions. We had a few modules importing the old name, which caused them

to fail to load and in turn broke the Django apps, preventing unit tests

from running.
This change updates those imports for the new names, allowing the test

suite to at least attempt to execute.

The test suite was able to run on Python 2.7, 3.4, 3.5, and 3.6 without

immediately and entirely failing. Along with all upcoming changes, the

tests involving these imports pass.
