[Fix]: Cancelling permission request dialog does not fire continuation

[jinliu9508]

Description

One Line Summary

Add a OnCancelListener to permission prompt so that dismissing (clicking outside of the dialog box) is treated as denying permission.

Details

Motivation

We want to correctly update the permission grant status to false when the user dismisses the permission request prompt without either rejecting or accepting it.

Scope

Clicking outside of permission request box will now treated as denying the permission. This will works for both notification permission and location permission.

Testing

Manual testing

Step to reproduce:

1. Turn off notification permission in app setting
2. Open the app and prompt for notification permission
3. Click outside to dismiss the alert dialog asking to allow OneSignal to send notification
4. Click outside to dismiss next dialog directing to app settings
5. Notice that the break point at onDecline is reached; this is not the case before the fix.
