* Fix tests now that we do permissions in a more standard way.

Rather than manually setting the permission class we previously
explicitly raised a PermissionDenied exception.  The way DRF
permissoning logic works, if we use the WWW-Authenticate header in the
highest priority auth class, it will return a 401 instead of a 403.


* Added test to make sure having permissions gives access to user mapping api

* Test new filters logic.

Ensure that the filters we add to the application access model make it
into the JWT correctly.

* quality fix
