Code review comment for lp:~veebers/unity8/update_ap_tests_ready_for_py3

I thought we wanted land this first, as we *will* cause failures during CI test running if we pull in python3-autopilot at this point. Francis wanted some package to experiment with to teach the CI infrastructure about using "autopilot" vs. "autopilot-py3" according to the dependencies, but that's not there yet.
