Actor can have torch missing when torch animation is played

This bug can occur at least in two cases when shields holstering is enabled and its animations are present:

1. For NPC's after combat in 0.47. From what I can tell, it is because timer from !501 (merged) can replace shield to torch in the middle of shield unequipping animation.
2. For player character when you equip torch instead of shield when shield unequiping animation is playing, in both 0.46 and 0.47.

I see two possible solutions here:

1. Cancel "shield" animation when a light source is equipped instead of shield
2. Ensure that the item in the left hand is shown when we play a "torch" animation.
