ZF-4310: OpenId check_immediate shouldn't return cancel
In continue of issue ZF-3348
Zend_OpenId_Provider returns "openid.mode=cancel" in check_immediate mode (protocol version 1.1). But OpenID 1.1 specification says (par. 18.104.22.168.) that "openid.mode" must be always equal "id_res" in check_immediate mode, regardless of positive or negative response. For all awailable for me OpenID 1.1 consumers "cancel" response immediately breaks auth process.
