AI's low-hp hero sometimes can't use healing potions correctly.

I have seen multiple times that AI's dying hero didn't use the healing potion it had. It's hard to find where this bug comes from. But this time I find a special case that is worth writing a new issue. As you can see, AI's orc hero was retreated by using a town portal. Tauren Chief was in bad shape but it didn't have a healing potion. The healing potion was in Farseer's bag. After they reached home, Farseer passed its healing potion to Tauren Chief, which is a rare situation. Soon Farseer was killed by the enemy's Death Knight. Tauren Chief didn't use the healing potion even if it was targeted by Death Knight. So it died unsurprisingly.

In this scenario, I think there are two possible reasons why this kind of bug might be triggered. First, AI's hero may not use healing potions correctly after using a portal. Second, maybe it's the swap of the healing potion between the two heroes that caused this bug.

Item use and control in inventory is primarily coming from hardcoded logic. We might be able to add extra logic to make sure the potion is used if they are dying though.
