  When you try to select a new project on the project dropdown, the
  project doesn't change. The commit below has introduced this bug on
  Horizon's master and has passed the tests verifications.
  
  https://github.com/openstack/horizon/commit/16db58fabad8934b8fbdfc6aee0361cc138b20af
  
  For what I've found so far, the context being received in the decorator
  seems to be the old context, with the token to the previous project.
  When you take the decorator out, the context received by the
  "can_access" function receives the correct context, with the token to
  the new project.
  
  Steps to reproduce:
  
  1 - Enable Identity V3 (to have a huge token)
  2 - Log in on Horizon (lots of permissions loaded on session)
  3 - Certify that you SESSION_BACKEND is "signed_cookies"
  4 - Try to change project on the dropdown
  
  The project shall remain the same.
