nativescript-local-notifications: Conflict between nativescript-local-notifications and nativescript-plugin-firebase on iOS

I was using version 3.0.0 of nativescript-local-notifications with nativescript-push-notifications and, as far as the limitations of that other plugin allow, everything was working fine on iOS.

However, after replacing it with nativescript-plugin-firebase, it’s not possible to schedule and display a local notification anymore:

Step by step, this is what’s happening:

• nativescript-plugin-firebase receives a remote push notification and calls the onMessageReceivedCallback with the following Message (as long as the application is on the foreground, even thought the Push Notifications Capability is enabled):

  {
      "adb_deeplink": "...",
      "message": "...",
      "attachment-url": "...",
      "from": "...",
      "foreground": true,
      "data": {
          "adb_deeplink": "...",
          "message": "...",
          "attachment-url": "...",
          "from": "...",
          "foreground": true
      }
  }
  

• nativescript-push-notifications schedules a local notification using that data with no at set and forceShowWhenInForeground: true and the following message appears on the console:

  CONSOLE LOG file:///app/tns_modules/nativescript-plugin-firebase/messaging
  /messaging.js:463:20: >>>>>>>>>>> Handle push from foreground
  

• onMessageReceivedCallback from nativescript-plugin-firebase is invoked again with the following Message:

  {
      "forceShowWhenInForeground": true,
      "foreground": true,
      "data": {
          "forceShowWhenInForeground": true,
          "foreground":true
      }
  }
  

• ∞

If the App is in background, onMessageReceivedCallback won’t be called until the App is opened, but then the same whole thing happens.

Tested on an iPhone 7 with iOS 10.3.1.
