[CHORE] Use react-native-firebase (#928) We need to migrate from deprecated react-native-fabric to react-native-firebase. This PR enables following Firebase features: * Analytics * Crashlytics * Performance It also tracks screen view without the necessity of HOC. Future work: I won't do it in this PR because it's large enough, but we need to log more app events, like 'sent_message', 'open_admin', 'media_upload', etc.
