tests failing with python 3.7.0

[dvzrv]

I'm currently tring to ship this as a package on Arch Linux [community]. However I'm unable to get the tests to run:

/usr/lib/python3.7/site-packages/nose/plugins/manager.py:395: RuntimeWarning: Unable to load plugin noseprogressive = noseprogressive:ProgressivePlugin: No module named '__builtin__'
