[fix] no notification in tray when app in foreground (like firebase)

[kreativ-software]

Normally push notifications don't appear in the tray when the app is in foreground.
Like done here: https://github.com/invertase/react-native-firebase/blob/3582e4865f5da49ba8b70b8681a03b7ba372aa51/packages/messaging/android/src/main/java/io/invertase/firebase/messaging/ReactNativeFirebaseMessagingService.java#L60

Looks good to me. Thanks @kreativ-software!

This isn't a fix at all, this is changing how the software works.

This is considered to be a a critical regression by one of my clients in which we use this library as being able to view the notification history in the system bar is a huge boon as opposed to it having no record at all if they missed it or ignored it while the app is in the foreground.

It would be nice if this had been left as an option or flag that could be passed rather than just merged in like that to suit somebody elses needs while breaking others. Now currently I have to fork and maintain this library or roll back at the same time as losing the other fixes that were part of the latest version bump.

@CDBridger The scenario that you've described makes sense to me. I may add a flag to enable that behavior when registering for notification hub in the next release. Sorry for your inconvenience.
