Cache ItemMeta instead of creating a new ItemMeta for each potion check (#5075)

* Cache ItemMeta instead of creating a new ItemMeta for each potion check

* Check if the item has item meta and, if it doesn't, bail out

* Also cache the potion item meta too

* Add requireNonNull to the potionItemMeta
