Code review comment for lp://qastaging/~fginther/ubuntu-test-cases/add-reminders

Ok, it turns out this is all due to a bug. phablet-test-run is trying to import reminders to decide if it's python2 or python3, and due to the deprecation warning from uitk, it decides to run python2, which is not even installed. xnox has a fix for this in phablet-tools and is going to get it landed. I suspect there are other tests like this too, and we were just getting lucky enough with them to run them after something that depended on python2 and installed it.
