Request to Identity provider is attempted even if authorization code is null, logging an error.


Looking at GoogleOAuth2AuthenticationHandler.AuthenticateCoreAsync(), if there is no 'code' parameter in the query string, a request is still made to googles endpoint attempting to exchange it for an access token. Google simply returns a 400 Bad request, which is then logged as an error.

This is a common case, as google redirects to the return url without the authorization code if the user doesn't give permission to the app.

I don't think this should be logged as an error, it would be better to log it at the info level with a more informative message.
