[MC-11788] Spawner that spawns zombie villagers that are being cured causes NPE

I created a spawner that spawns zombie villagers that are being cured. When I open the world in minecraft, it crashes with an NPE.
After investigating it in MCP, I found that it's caused by a zombie villager model in the spawner. It uses a dummy entity, with world (a.k.a. level) being set to null. But when a zombie starts curing, it accesses the world. A simple if (world != null) should fix it.

Maybe related to MC-10587?

Is this still a concern in the current Minecraft version? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.

No answer, assuming no longer an issue.
