[V20.7 - Ground Combat] Shield not functional when other hand empty

[llunak]

A shield is not rendered and does not appear to be functional when the other hand is empty.

Steps to reproduce:

- Start a new game, place base.

- Change the role of one soldier to 'Shield'.

- Start ground mission.

- The shield soldier will have shield in one hand and pistol in the other hand. Note that the soldier is rendered as having a shield.

- Go to inventory and drop the pistol. Now the soldier is rendered as empty-handed, even though the control panel at the bottom shows that the soldier has the shield in one hand.

- It appears that this is _not_ just a rendering problem, as I had a soldier single-shot by a plasma pistol (on veteran) despite having a shield and facing the alien (unless it is possible for an alien to manage this despite a shield, but I've never had this so far when having a shield equipped "correctly").

I take it back, the shield does work even if not rendered, the soldier in the original test was just unlucky and got shot despite the shield. So this is just a rendering problem.
