Pokechu22 44dd60ac27 SPIGOT-3272: Fix duplicate creative inventory 
This change properly identifies the creative inventory as one with 5 crafting slots (as that's the default set in ContainerPlayer, and handled properly in other containers), instead of having the same inventory twice (which breaks slot identification).
