Some mobs that are wearing armor, do not properly render / show the armor.

I tested this by dispensing armor onto all the "humanoid" mobs in the game, like zombies, skeletons etc. The only mobs that currently don't render armor properly are: Evokers, Vindicators, Witches and Pillagers.

How to reproduce:
1. Put a full set of armor into a dispenser.
2. Point that dispenser into a mob of your choice, power the dispenser.
3. Depending on the mob it will be placed onto it, and render properly.
4. Some mobs won't properly render armor, see list above.

Figured i would bring this bug to attention, since it was recently fixed for wither skeletons. You can see this bug in action here: https://youtu.be/ljJdahgNzqo?t=560
