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

Right, I think I need to clarify what I had intended.

I noticed that the changes made here cannot be consumed by other python3 versions of tests when I started checking the compatibility of the ubuntu-keyboard tests that use the unity8.process_helpers.
This is why I wanted to change the packaging so that the tests, and more importantly the emulators, were installed for python 2 and python 3 (so I could proceed with the u-kb stuff).

This comment made on the ui-toolkit is topical: https://code.launchpad.net/~chris.gagnon/ubuntu-ui-toolkit/autopilot-python3-package/+merge/196358/comments/454927
(effectively either split into 2 packages or insanity of dual-installation).

I get the feeling that at this stage that I should alter what I have so that it is split into 2 packages.
