Named items bugs

There are some bugs with named items:
Pls look at the screenshots first 🙂

1. Named minecartchests will drop the minecart and the chest when getting destroyed (in creative!)
2. klicking with mousewheel at the named minecartchest will give you a normal minecartchest
3. Only the dropped minecart (look at 1.) will have the name, the chest is still a "chest"
