Issue Description:

Dogs picking up items that stack will apply NBT data to newly picked up items, allowing for dupes.

Steps to reproduce:

1. Name a stick
2. Put it into the first slot of a Doggy with level 5 Pack Puppy
3. Throw it an unnamed stick.
4. The NBT is transfered to the new stick and it too will get named
5. Do this with a drawer filled with Diamonds instead and drop an empty drawer and it will fill the drawers.

Hey there @percivalalb, any estimated date for when this fix will be published on Curse?

I am sorry for the very delayed release fix is now in v1.15.1.6. I would recommend you update to 1.15 or 1.16 once there is a recommended version of DT2.
