Vindicators, pillagers and vexes raise both of their arms when attacking a player if they don't have any weapons

Due to the fix of MC-158735, MC-176836 and MC-181925, I would have expected vindicators, pillagers and vexes to not raise their arms at all when attacking a player without weapons. However, they now raise both of their arms, similar to zombies, which looks a bit silly.

To reproduce

1. Summon a vindicator without a weapon

   /summon minecraft:vindicator ~ ~ ~ {HandItems:[{},{}]}

2. Summon a pillager without a weapon

   /summon minecraft:pillager ~ ~ ~ {HandItems:[{},{}],Patrolling:1b}

3. Switch into Survival mode
   → The pillager and the vindicator both raise both of their arms
