There was a complicated tox setup, and Travis installing tox to nominally check multiple configs. Except, that it then ignored all of that and just ran tests with the default Python! This PR makes it actually use tox in CI, removing a bunch of configs that just didn't work, and explicitly specifying various Python versions so the tox runs get the version they need.
