ZF-3348: OpenId check_immediate without log in shouldn't return cancel


OpenId check_Immediate with logged out User returns "openid.mode cancel" instead "openid.mode setup_needed" . The dump of the validator on… returns:

  Redirecting to <a rel="nofollow" href="">;</a>
  openid.identity   <a rel="nofollow" href=""></a>
  openid.mode   checkid_immediate
  openid.return_to  <a rel="nofollow" href="">;</a>
  openid.trust_root <a rel="nofollow" href="">;</a>
  Response received:
  action    response
  attempt   1
  nonce YW7sK1df
  openid.mode   cancel
  openid.user_setup_url <a rel="nofollow" href="">;</a>
* Operation Cancelled.


Please assign and categorize as necessary. I've preliminarily targeted a release.

Fixed only for OpenID 2.0, because OpenID 1.1 specification says nothing about "setup_needed" response.

Updating for the 1.6.0 release.
