Expected Behavior

Shulker boxes should retain their inventory when painted

Actual Behavior

Shulker boxes lose their inventory when painted

Steps to Reproduce

Place shulker box.
Insert item into shulker box.
Paint/unpaint the box.
Observe that it's now empty.

Additional Information

This is caused by the ColorSprayBehaviour not copying over the inventory when replacing the shulker box block.
