Disc in Jukebox gets deletet with pipes

**Versions**

CraftBook version: 3.10.5
Bukkit version: 1.18.1

**Describe the bug**
If you pipe in a music disc into a jukebox it only works if a disc is already in the jukebox. It also deletes the old disc when the new one is insertet.

**To Reproduce**
- create a simple pipe system
- put a jukebox to the end
- try to pipe a disk into the empty jukebox
- add disc to the jukebox
- activate the pipe again

**Expected behavior**
- it should be vise versa i think
- only pipe in the disc when the jukebox is empty so the disc gets not deleted
