Raise flake8-import-order version to latest
We had this library capped at a release that is a few years old. Now
that we have dropped py2 testing, we can pick up the latest version.

This uncovered a few things to clean up. Mostly the fact that mock is
now a part of the StdLib unittest since Python 3.3.
