Wrong call to hoauthAfterLogin while checking for hoauthProcessUser method

I didn't see hoauthProcessUser callback documented anywhere, but I think there was an error HOAuthAction.php, maybe due to a copy&paste.
After checking existence of hoauthProcessUser, I'd expect to call that method, not hoauthAfterLogin.
