Description

Right now when roles a re set current, we do nothing to optimize requesting for privileges. We basically get all roles, and then use the intersection to further filter the roles. After which we get privileges.
There should be a better approach to this. We should simply use those current roles, and return privileges for them. We don't even need to check if the current roles belong to the user-groups because that is something that should've been checked earlier when making roles current
