openAuth does not work for iOS13

[jalbatross]

openAuth does not work for iOS13. An error is thrown when trying to start the ASWebAuthentication session:

Error Domain=com.apple.AuthenticationServices.WebAuthenticationSession Code=2 "Cannot start ASWebAuthenticationSession without providing presentation context. Set presentationContextProvider before calling -start." UserInfo={NSDebugDescription=Cannot start ASWebAuthenticationSession without providing presentation context. Set presentationContextProvider before calling -start.}

This is likely due to the new API for the class introduced in iOS13:
https://developer.apple.com/documentation/authenticationservices/aswebauthenticationpresentationcontextproviding?language=objc
