Title: Fix error in authentication + changing passphrase

The problem flow was:
Visit Client app (e.g. publisher).
Redirected to signon
Login to signon
Password change required
Change password
Error message saying "The authoprization server does not support this response type."

The underlying cause was that devise_security_extension was returning you to
the request.path, which excluded the querystring, which the OAuth flow needed.
The fix was to change the gem to return you to the fullpath.
