Custom Horse Conversions Duplicate Armor

Addon Description: This addon allows for a horse to be converted to a zombie horse when struck with lightning using similar components to drowned conversion. However, there is a duplication bug that arises from using this behavior.

Expected Behavior: When converted from Horse to Zombie Horse, it retains armor and saddle, or drops them like a Drowned.

Observed Behavior: When converted, it retains a saddle rendered but does not have one in its inventory, and drops 2 armors and a saddle, effectively duplicating them.

Steps to Reproduce: 
1. Download the attached behavior pack
2. Summon a vanilla horse
3. Equip it with a saddle and armor
4. Strike it with lightning to convert it to a zombie horse (addon behavior)
5. Observe armor duplication, saddle drop, and false saddle rendering
