Error when items are unequipped

[nasapunk88]

Currently if you are missing any item (using a 2h, missing offhand) it error's out.
The problem is that itemString is nil when there is no equipped item and is then passed to "GetItemInfo(itemString)", causing the error.
A quick fix is just making sure there is an item equipped before calling the function,
inside ItemLevelOverlay.lua, line 24:

local function getInventoryItemLevelFromInventorySlotName(inventorySlotName)
local inventorySlotNumber = select(1, GetInventorySlotInfo(inventorySlotName))
local inventoryItemLink = GetInventoryItemLink("player", inventorySlotNumber)
if inventoryItemLink then
return ItemUpgradeInfo:GetUpgradedItemLevel(inventoryItemLink)
else
return nil
end
end

I'm with every slot equiped here, and the problem still happen. Every time, on ui load. Might be that and something else.
