Don't you do the clean up from this TODO in UseRManagerImpl now. Maybe you can
clean up this todo if this is the case.

No, I only clean up device-local accounts that no longer exist. The UserManager
does not reason about the whitelist and hence, will not clean up the users
referenced in this TODO.
