ANDROID : can't find notificationID

1. What version of RN and react-native-fcm are you running :
RN0.54 / "react-native-fcm": "14.1.3"

2. What device are you using?
Samsung S7

3. Is your app running in foreground, background or not running?
This is a general case, the notificationID is simply not there.

```
FCM.on(FCMEvent.Notification, notif => {
console.log('notif', notif)

// notif.notificationID === null ...

const { status, notification: { deliveredNotifications } } = getState()
deliveredNotifications.forEach(notifId => FCM.removeDeliveredNotification(notifId))
dispatch(notificationActions.removeAllDeliveredNotifications())
dispatch(notificationActions.deliveredOneNotification(notif.notificationID))

if (notif.status_id) {
if (!notif.opened_from_tray) {
_showLocalNotification(notif)
}
_dispatchNotif(dispatch, notif)
}
})
```
