To re-create on the villager part, do ./gamemode creative, summon a husk and summon a villager. The villager will react as you'd expect, by running away from the husk but the husk won't pay any attention to the villager.
To re-create on the villager_golem part, do ./gamemode creative summon a husk that can withstand the golem's attacks (invincible, preferably) and summon a villager_golem. The golem will attack the husk but not vice versa.
