Shield sheathing does not work properly

1. Setup a weapon + shield sheathing
2. Install shield equipping animations
3. Equip a shield and a one-handed weapon
4. Switch to 3d-person view
5. Use a key binding to draw/holster the weapon

Note that shield equipping animations support was a part of shield holstering feature since it was ever implemented.

In release 0.48, player character moves shield between left hand and back. In 0.49 and newer PC just plays a shield (un)equipping animation (an equipped shield remains holstered). This issue also affects NPCs:
