[MC-140922] Zombie Villagers don't wear armor properly

When a zombie villager spawns with pants the armor is bugged because of the new textures.

Command to summon zombie villager with armor, for convenience:

/summon minecraft:zombie_villager ~ ~ ~ {ArmorItems:[{id:"diamond_boots",Count:1},{id:"diamond_leggings",Count:1},{id:"diamond_chestplate",Count:1},{id:"diamond_helmet",Count:1}]}
