fix(live activities): Register push tokens in more places

* Apple has confirmed that when using push-to-start, it is best to check both Activity<...>.pushToken in addition to Activity<...>.pushTokenUpdates --- as well as checking Activity<...>.activities in addition to Activity<...>.activityUpdates --- because your app may need to launch in the background and the launch time may end up being slower than the new values come in. In those cases, your task on the update sequence may start listening after the initial values were already provided.
