Fix Player Inventory not updating when in Creative Tabs

[ALongStringOfNumbers]

When in Creative, and in one of the Creative Menus, giving yourself an item from JEI (Using inventory mode as the give mode and with a full hotbar) and then switching to the player inventory will see that the player inventory has not updated. The block will be in the inventory, but will be invisible.

It will sync if you give yourself another copy of the same item from JEI, then displaying that there are two items.

You can desync your inventory if you move something from your hotbar into the slot that the item would be added into and then give yourself another copy of the item. Then your inventory will think you only have 1 copy of the item.
