Problem: CAS/Shibboleth User Role not "Applied" after logging in first time

[misilot]

Current Behavior

Steps to reproduce the behavior

1. Enable CAS
2. Setup CAS For groups
3. Add user to say "administrators" group
4. Login as user
5. You see they do not have access to settings, etc...
6. However, if you look at the user it shows they are an administrator

What I think is happening is the interface gets cached as an authenticated user, and they can't see any of the settings until the cache is cleared or we run php symfony cc. My guess is because the role is being added in later in the flow?https://github.com/artefactual/atom/blob/qa/2.x/plugins/arCasPlugin/lib/casUser.class.php#L116-L131

Expected Behavior

User Logs in and gets appropriate permissions, without having to have cache time out.
