REGRESSION(276009@main): Crash in
ApplicationStateTracker::applicationDidEnterBackground()
https://bugs.webkit.org/show_bug.cgi?id=272241
rdar://125895046
Reviewed by Eric Carlson.
>From crash reports, it appears that the NSNotificationCenter observers are
>being called after
the ApplicationStateTracker itself has been destroyed. Ensure these observers
are all
unregistered upon destruction, and additionally protect against the observers
being called
after unregistration by passing a WeakPtr into the observer's lambda.
