Skeletons shoot arrow without bow in powder snow

Steps to reproduce:

1. Load the attached world.
2. Set your gamemode to surival.
3. If the skeleton converts to a stray, summon a new skeleton wielding a sword using the command blocks.

Observed results:
The skeleton will continue to shoot arrows despite having its bow changed to a sword.

Expected results:
The skeleton shouldn't shoot arrows when its bow has been replaced with a melee weapon.
