CI tests invariantly running on python 3.5

[hockeybuggy]

Not sure what the cause is yet, but it seems that tests are running on python 3.5 in every build on travis.

e.g.
From build 168155582 py27-dj18

$ python --version
Python 3.5.2

and py35-dj18

$ python --version
Python 3.5.2

how sure are you? line 172 which comes after that is what should be settings the version used during tests iirc:

 tox -e $TOX_ENV

regardless of the default python on the box

Ah you're right. So the "system python" in all of the builds are and the venvs use different pythons.

From the cat .tox/$TOX_ENV/log/*.log call at the end:

cmdargs: ['/home/travis/virtualenv/python3.5.2/bin/python', '-m', 'virtualenv', '--python', '/opt/python/2.7.9/bin/python2.7', 'py27-dj18']

Thanks @JBKahn . Nothing to see here.
