This queries the user object, and returns all roles the implementation
decided to return. Standard user folder only returns 'Authenticated' in
addition to the roles explicitely given to that user....
(FWIW in CPSUserFolder we chose to return Authenticated as well as
Anonymous to be consistent.)

...but from the security machinery's point of view, if an object or
method is protected by a permission given to the role Anonymous, then
any user will have access. ImplPython.validate has:
# Short-circuit tests if we can:
if roles is None or 'Anonymous' in roles:
(roles here is the roles issued from the permission on the object considered.)
