Studio Administration interface does not properly grant admin privileges

[rtibbles]

Observed behavior

Toggling a user as admin in the Administration interface of Studio set the is_admin property to true. However, the Django REST framework IsAdminUser permissions class checks against the is_staff property, which is not set.

Expected behavior

Either we should use a permissions class that checks for is_admin or we should also be setting is_staff when we toggle admin permissions.

User-facing consequences

Newly updated Studio admins face considerable consternation and concern.

"Newly updated Studio admins face considerable consternation and concern" The described mismatch between my expectations and described state of the issue is somewhat less reassuring than anticipated.
