The purpose is to ensure that new preferences that are in neither list get the appropriate enabled/disabled setting without having to utilize the savefile update path.
Also attempts to optimize the acquirement of the preference mob.
For reasons unbeknown to me, the client var is reset when the client logs outs and thus the preference mob cease to be.
Now stores the client key, and acquires the appropriate mob based on that, if possible.
Also removes the sanitation check because the holder isn't set before the preferences are created.
