[GH-ISSUE #700] Canceling Apple ID isn't handled

We use Azure B2C to handle authentication and OAuthSwift to handle that communication. Everything works great and has for quite some time.

I have no idea what to try next - it seems to me that OAuthSwift should be able to detect the user cancelling out of the Apple ID auth just like it does when the user cancel's out of any IDP shown in the browser window.
