Subject: [PATCH] lib: Destroy and re-create the control proxy if the server changes

Although I don't think this shouldn't be required as org.freedesktop.PackageKit
is a well-known service, it seems that from gnome-software we need to manually
disconnect and reconnect when packagekitd is restarted.

Weirdly, gnome-packagekit isn't affected in the same way.
