Use --source to ensure tests are showing what we want.

Travis started having these extra files in coverage reports from our
tests:

site-packages/pkg_resources/_vendor/six.py
site-packages/pkg_resources/extern/__init__.py

I don't know why they are being pulled in, but the tests aren't
interested in them, and it is throwing off the results.
