Subject: [PATCH] Update Chest Animation when Cancelling Event

Update chest animation after cancelling InventoryOpenEvent. Fixes BUKKIT-1440

Currently if a plugin cancels an InventoryOpenEvent for vanilla chests,
the chest animation for clients is stuck in the open state since
IInventory's closeChest method is never called. To fix the issue, closeChest
is called before exiting the display GUI method.
