Renamed campfires show their name when looked at

The bug

When a campfire is renamed in an anvil and placed, it displays its name as a name tag when looked at, like an item frame would.

How to reproduce

1. Get a campfire
2. Get an anvil
3. Rename the campfire in the anvil
4. Place it
5. Look at it

Note

Campfires don't even preserve their name when broken, so there's really no reason to store it in the first place.
