"UI API called on a background thread" when calling openSettings

[joprice]

When openSettings is called on ios, it results in the following error:

Main Thread Checker: UI API called on a background thread: -[UIApplication openURL:options:completionHandler:]
PID: 68586, TID: 67417523, Thread name: (none), Queue name: com.meta.react.turbomodulemanager.queue, QoS: 

The resulting destination also ends up being the base settings page, and not the app-specific settings (This may be an separate bug).

For the first issue, wrapping the call in DispatchQueue.main.async { should fix it. The second one might be a simulator-specific issue, as it is routing to the correct place on a real device.

For the second issue, I found in the console the error like

Destination 'SettingsURLDestination: { url: 'app-prefs://?[MY_BUNDLE_ID]&target=com.apple.settings.notifications', action: 'Navigation: notifications', queryItems: [root=NOTIFICATIONS_ID,path=[MY_BUNDLE_ID]]}' is for a selection not possible currently 'notifications', stashing as pending and returning.

so it seems to be an issue with the simulator.
