1317275 - Run pip v9's new 'pip check' feature during the test run

Status: RESOLVED FIXED

(Tree Management :: Treeherder, defect, P3)

Description

[Ed Morley [:emorley]]

The just released pip v9 includes a new `pip check` feature, which ensures there are no incompatibilities in the currently installed Python packages.

This would have caught the issue in bug 1312096, so we should enable it on Travis/runtests.sh.

This would have also saved an hour of debugging whilst working on bug 1324707.

(Turns out djangorestframework-filters had pinned to a less-than-latest version of django-filter, but this wasn't apparent after having updated requirements/common.txt by hand, resulting in obscure exceptions).
