James Clarke a575e6b075 Use correct itemstack for dispenser behavior chaining. Fixes BUKKIT-2886
When an event changes the item to be dispensed we check to see if the new
item has special behavior for dispensing and if so pass it on to that
behavior handler. However, we are actually checking the old itemstack and
passing the new itemstack so this check fails.
