The lead will be still attached when we use command to kill the allay.

When we kill the allay on a lead using the command it will not update properly and it will still be on the fence.

Steps to reproduce:

1: summon a allay and attach it to a lead.

2: using the command " kill @e[type=allay]" to kill it.

3: the fence will not update and the lead will still stay on the fence.
