App doesn't cleanly shutdown on quit

[ara4n]

If run on macOS, Cmd-Q doesn't quit the app. Eventually it gets terminated in the bg by the OS:

2022-12-23 14:41:12.997720+0000 ElementX[79926:3533289] [BackgroundTask] Background Task 71 ("SuspendApp: EAD5BC66-AC64-4E7E-82F1-5060591B698C"), was created over 30 seconds ago. In applications running in the background, this creates a risk of termination. Remember to call UIApplication.endBackgroundTask(_:) for your task in a timely manner to avoid this.

I'm going to close this issue in favour of #438 regarding the background task.

Its worth pointing out though that running iOS apps on Apple Silicon Macs have a different lifecycle to macOS apps. Quitting the app does the equivalent of backgrounding it on iOS as the app isn't aware of the normal macOS app lifecycle. This would be one of the advantages of switching to Catalyst for the Mac app I guess.
