Gnome Software re-prompts uninstall of software

[Ty Young]

Gnome Software re-prompts removal of software, even though the software was just removed. Clicking on remove again may either result in the software being displayed as not installed correctly or say that the removal had failed.

To reproduce, hit "remove" on any installed software listed under "installed" or by searching from the store itself and attempt to remove the software from either the installed software tab or in the search results.

I can confirm that this is occurring. I removed Empathy from the Installed list, it displays that it's being removed, the view is then refreshed, but it was still listed with the Remove option. If you run apt-cache policy empathy, it's no longer installed:

empathy:
  Installed: (none)
  Candidate: 3.12.11-0ubuntu3
  Version table:

From the package information page, the remove button behaves correctly.
