Subject: [PATCH 2/2] TelegramClient exposes Session as a property so that
 TLUser can be retrieved by application in case the sign in process is
 bypassed.

Example code:

                if (client.IsUserAuthorized())
                    user = client.Session.TLUser;
                else
                {
			/* sign in or sign up */
		}
