Debugger: DevTools/Metro is disconnecting from the websocket if the app is backgrounded - was: `AppState.addEventListener('change')` on Android seems to suddenly stop working

Description

AppState.addEventListener('change' on Android seems to suddenly stop working.

Steps to reproduce

https://github.com/NorseGaud/expo-testing

npx expo run:android

Once up and running, background the app by switching to something like the Contacts app. Then, open a contact, create a contact, etc, and then come back. You won't see the active log. However, if you just background the app and don't do anything significant it will show active logs switching back.

Starte mit dem verpflichtenden Reproducer unter github.com/NorseGaud/expo-testing und führe npx expo run:android aus. Versetze die App in den Hintergrund, verwende eine andere App, kehre zurück und vergleiche die AppState-Logs mit der DevTools/Metro-WebSocket-Verbindung; abgeschlossen ist die Aufgabe, wenn das Versetzen in den Hintergrund die erwarteten active-Logs oder die Debugging-Verbindung nicht mehr verhindert bzw. trennt.
