Piglins with NoAI shake in the overworld

Piglins summoned without an AI (using NoAI:1b) will still shake in the overworld, even though they will never actually be zombified.

Steps to reproduce
1. Summon a piglin in the overworld using /summon minecraft:piglin ~ ~ ~ {NoAI:1b}
2. Observe the piglin shake is if it is going to be zombified
