Remove unused "outfits#new newest_items" cache

Huh! This cache key seemed to only be referenced in checks and expirations, but was never actually used! So I guess we've been loading the modeling predictions every time for a while huh??

We'll get smarter about that someday, but anyway, that lets us delete our Item resque tasks and ItemObserver!
