Code review comment for lp://qastaging/~tpeeters/ubuntu-ui-toolkit/09-desktop-toolbar

Tested on mako with image 272:
- Manually tested gallery-app, system-settings, camera-app.
- AP tests for address-book-app, messaging-app OK.

gallery-app tests fail with
File "/home/phablet/autopilot/gallery_app/emulators/main_screen.py", line 9, in <module>
from toolbar import Toolbar
ImportError: No module named 'toolbar' http://paste.ubuntu.com/7190772/
see http://paste.ubuntu.com/7190772/
This seems like a problem in gallery-app. See elopio's fix: https://code.launchpad.net/~elopio/gallery-app/override_toolbar/+merge/213703

There was one failure with unity8: http://paste.ubuntu.com/7191141/

Still need to run UITK tests.
