React-native-onesignal: React-native-onesignal and ios 13.1

Description:

We're in the process of updating react-native-onesignal in an app - react-native is version 0.55.2. The issue in short is, that we've tried updating the react-native-onesignal sdk (to 3.3.2 and 3.3.3) per the email being sent out regarding xcode 11 and iOS 13. However, when running the app on an iOS 13.1 device (iphone 7) (it is built and run with xcode 11) the app runs, it gets the popup asking for permission to send push notifications (and we accept) but we always get the following in the console and the app won't register for notifications, as in the device doesn't show up in the Onesignal dashboard:

(I do not know how to format the code, sorry )

Environment

Steps to Reproduce Issue:

1. Install version 3.3.2 or 3.3.3 of react-native-onesignal
2. The SDK is initialized in App.js
3. Run the app on an iphone 7 with iOS 13.1 and accept push notifications on the popup.

Anything else:

We have tried running on iOS 12.4 devices with react-native-onesignal 3.2.4 (pre-update), 3.3.2 and 3.3.3 all of which work there. It uses the old identifier format as expected. We have run the Live version of the app on an iOS 13.1 iphone 7 which works (we thought it shouldn't work). We have run the updated app with 3.3.2 and 3.3.3 which run on the emulator just fine. It gets to connect, it just doesn't get the popup asking for push permissions as expected.

We are going to try and see if we can get a device running iOS 13.0 and test there since the emulator is 13.0 and there might be a difference from there to 13.1.

For now we can't get further on our own and have already spent days running in circles.

Appreciate the help!
