[🐛] An empty remote message is displayed if the notification is swiped while the app is open.

[Augustach]

Issue

Hey, first of all, thank you for such a brilliant package!

I get an kinda empty remoteMessage in some case:

1. The app is in the background.
2. A notification is received.
3. Open the app from background mode.
4. Open the notification tray and swipe the notification.
5. The onMessage callback is called with the following empty data: {"sentTime": 0, "ttl": 0, "data": {}}.

I tested it only on Android 14.

So, is this a bug, or should I handle such cases in a specific way?

Have you converted to AndroidX?
