PyGIWarning: UbuntuAppLaunch was imported without specifying a version first

[Carla Sella]

When launching Autopilot tests for Music App you get an error indicating that UbuntuAppLaunch was imported without specifying a version first.
This is the error:

autopilot run music_app
/usr/lib/python2.7/dist-packages/autopilot/application/_launcher.py:23: PyGIWarning: UbuntuAppLaunch was imported without specifying a version first. Use gi.require_version('UbuntuAppLaunch', '2') before import to ensure that the right version gets loaded.

Thank you for taking the time to report this bug and helping to make Ubuntu better.

This is an issue that is related to python gi on Xenial (16.04), therefore I am adding pygobject to this bug and as it affects all the core apps which use this kind of import I'm marking this as invalid for music specifically.

Fix committed into lp:autopilot at revision None, scheduled for release in autopilot, milestone 1.4

PyGObject warns that gi.require_version() wasn't used. That's something that needs to be fixed by the library user.
