Handle LOGOUT_URL=None in the logout view

Browse source 
The view used to crash when `LOGOUT_URL` was not set and the user was
connect via CAS.

Cause: we assumed the result of `LogoutView.get_next_page()` to be a
  string and tried to prepend the domain name of the site to it.

Fix: redirect to the CAS' logout view without any `next_page` parameter.
