iOS: Fix logic for determining whether to exit the root event loop

Instead of trying to hook into various places where we might be in a
situation where the root event loop should exit, and then enabling the
runloop-observer, we always keep the observer active, and then do the
relevant checks whenever the run-loop exits.

The reason for checking if the event loop is running is that iOS will
enter and exit the root runloop as part of normal operation, eg due to
flicking a scroll view and switching the runloop mode, so we need to
ensure that we're actually supposed to exit the root event loop.
