Module suddenly stopped working

[ma7moudAziz]

Hi @hansemannn,

You've done a great job to this module. I was using your module for some time for now until suddenly it starts giving run time error, I noticed those issues when google update their FCM messaging dependencies to 20.x.x (i don't know if the current issue is related to this upgrade).

And here is the code I am using to register to push notifications:

var core = require('firebase.core');

    if (OS_ANDROID) {
        core.configure();

        var fcm = require('firebase.cloudmessaging');

        if (fcm.lastData && !_.isEmpty(fcm.lastData) && fcm.lastData.data) {
            var notificationData = JSON.parse(fcm.lastData.data)
             //...
        }

        fcm.addEventListener('didReceiveMessage', addBadgeNumber);

        fcm.notificationChannel = Ti.Android.NotificationManager.createNotificationChannel({
            id: 'channelId',
            name: Ti.App.name,
            importance: Ti.Android.IMPORTANCE_DEFAULT,
            enableLights: true,
            enableVibration: true,
            showBadge: false
        });

        fcm.registerForPushNotifications();

        if (fcm.fcmToken) {
            //...
        }

        fcm.addEventListener('didRefreshRegistrationToken', function (e) {
            //...
        });
    }

the error received for android is the following:

Attempt to invoke virtual method 'com.google.android.gms.tasks.Task com.google.firebase.iid.FirebaseInstanceId.getInstanceId()' on a null object reference

And please help me with this since my release relies on this issue and I've already spent a lot of time trying to fix this issue. And thanks in advance. Best Regards.
