Iron golem AI becomes broken after getting leashed

Unleashing the golem from the lead causes their AI to be broken. When a mob is near the golem, the golem would sometimes walk and stop while sometimes losing focus on the targeted mob.

How to Reproduce

1. Create and leash an iron golem
2. Summon a husk with no AI
   → The golem's AI is not working as intended.

Workaround

Save and quit to title and re-enter the world, this fixes the iron golem's broken AI.
