Prevent game from closing from proximity/multi-tasking changes

XR_SESSION_STATE_STOPPING assumes that the OpenXR session can be resumed again and that the application temporarily closes it, which is quite hard with an emulator. Listening to the exiting event instead makes it so that you can still press the exit button in SteamVR/Air Link and it'll exit, but not listen to proximity changes.
