Unity-2d doesn't move focus to Webbrowser in Launcher, after click Bug Link in "update-manager"

[Bartosz Kosiorek]

Launcher in Unity-2d doesn't move focus to Webbrowser, after click Bug Link in "update-manager"

Step to reproduce:
 1. Start upgrade-manager
 2. select the package to upgrade and click on LP link (to see bug report in firefox)
 3. Firefox will open, and the focus will be on Firefox.
 4. Unfortunately in Launcher the focus is still on "update-manager", so you can't go back to "update-manager" from firefox

Tested on latest unity-2d 5.2.0:

$ apt-cache policy unity-2d
