Automatically uninstall the bundle after Quit if eligible.

For now, the requirements are:
* The bundle is installed and
* The bundle is per-user or has already elevated and
* No non-permanent packages are installed and
* No non-permanent packages are cached and
* No related bundle would run by default during uninstall and
* The bundle didn't Uninstall/Cache/Install/Modify/Repair and
* The BA didn't opt out of this behavior
