[MC-157192] Iron Golems attempt to attack player in Creative mode

I am not sure if they only attack in Creative if you switch from survival as they attack, but that's how i found out.

Environment

How to reproduce

1. Do anything to get them angry. (Example: Attack villagers or other things to have low gossip)

2. Go in survival and they will attack

3. Quickly switch to creative and they should still try to attack.

I reported the bug wrong I think.
