[Merge] lp:~fginther/phablet-tools/fix-ptr-python3-import-check into lp:phablet-tools

[Francis Ginther]

The proposal to merge lp:~fginther/phablet-tools/fix-ptr-python3-import-check into lp:phablet-tools has been updated.

Description changed to:

In phablet-test-run, check the return code when attempting to import tests with python3 instead of just looking for text output. Log messages generated on import will cause the import check to fail when it should not.

This was tested with the following:
 - mediaplayer_app (installed from mediaplayer-app-autopilot)
   This falls back to python 2.
 - calendar_app (installed via phablet-click-test-setup)
   This uses python 3.
 - address_book_app (installed from the packages used by https://jenkins.qa.ubuntu.com/job/generic-deb-autopilot-runner-mako/1149)
   This uses python 3 with this fix (w/o this fix it incorrectly uses python 2)
