Put the summary of the bug you're having here

What I expected to happen was...:
I named a squid so it wouldn't despawn.
What actually happened was...:
I left the chunk it was in to find that it had despawned.then when it did, I tested other mobs that could despawn to see if they would despawn when named too. they did.

Steps to Reproduce:
1. Name a mob.
2. leave the area.
3. come back to see it had despawned.
