removed method breaks backward compatibility

[David Lyle]

the remove_project_cache method was removed in https://github.com/openstack/django_openstack_auth/commit/3715a5f445254520f951a5d791fb5eeeeb2b2b57
this method is called from the liberty version of horizon.

The method definition should be added back in to fix backward compatibility.

    Fixing backward compatibility

    The remove_project_cache method was removed because the underlying
    functionality never really worked. Unfortunately, that method was
    called directly from Horizon in the Liberty release. An empty
    signature is being added back to fix backward compatibility.
