Issue Description:

When you automatically insert a soul shard into a cage it does not activate it. It actually binds the soul cage but does not do anything. Updating it with redstone doesn't change anything either. Manually taking it out with shift + right click works though.

What happens:

When you pipe a soul shard into a cage it does not activate it and does not spawn any mobs.

What you expected to happen:

When you pipe a soul shard into a cage it activates it and starts spawning mobs.

Steps to reproduce:

1. Pipe any tiered soul shard into a cage.
2. Block texture doesn't change but it says it is bound to a mob.
3. Wait for mobs to spawn.
4. Mobs don't spawn.
