fix old twitter api endpoint
OpenID sendToAuthenticationUri lacks promise

Openid module sendToAuthenticationUri step did not provide correct Promise object reference to use inside this.relyingParty.authenticate callback function. Also call back function did not fulfill promise(caused timeout error) and step itself did not return promise reference (caused uncaught exception).
