Skip test failing the release build

This test passes on dev builds but fails on release. We need to get a
deployment out the door so I am skipping the test for now.
Import skip into test module that requires it
Remove line length lint
Merge remote-tracking branch 'upstream/master' into release
Don't skip test because it's now fixed
Move code in treemap/management from __init__.py to util.py

Works around a problem building the production AMI, which has to execute a management command on a machine without a DB. Running a management command loads __init__.py, which crashed without a DB because there's a top-level import of models.
... but don't eliminate __init__.py
Merge remote-tracking branch 'upstream/release'
