expect it to behave. This patch is inspired by latest

Berrangé <berrange@redhat.com> I guess this points to a design flaw in our session daemon, albeit one that is rather tricky to fix. We really only want to autostart once, when the session starts, but defining the scope of a "session" for users is tricky. It is a little better defined in the systemd world though, so I wonder if there's a way to use that to selectively trigger autostart.
