InventoryManager: avoid useless work in trackItemStack()

Browse Source 
this attempts to accommodate slots being set to themselves, which is a rare enough occurrence (only plugins will cause it) that it doesn't make sense to penalize every inventory update this way.
attempting to avoid changing the itemstackID in this way is detrimental to performance, and it doesn't actually matter if we set a new itemstackID anyway.
