When the server requests a disconnect due to a user connecting
via a second device, the client will now log the user out on the first
device and show a notification informing them of the cause of
disconnection.
Optimally, I would like to remove the `Schedule` in `EndPlaying`, but it
turns out quite a few test are relying on this at very least. Adding a
paired schedule ensure that order of operations is correct, at least.
