Some oauth services require the redirect uri be configured on their service, and the reject the redirect_uri param if we send it. Chrome works fine in this scenario, but we have been requiring the redirect_uri be provided. This addresses that requirement by using our own default redirect url, which would be the url used to configure the oauth service.
