ZF-4310: OpenId check_immediate shouldn't return cancel

Description

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. 4.2.2.1.) 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.

See http://openid.net/specs/… and http://openidenabled.com/resources/openid-test/… for tests.
