GetLootSlotLink gives a link for the unscaled item

[kemayo]

GetLootSlotLink returns an itemLink that appears to be for some "default" version of the item, with a different item level than the item the player loots will have. Immediately following looting an item, the link obtained from the container functions will be different, so this probably isn't just #656.

My current workaround is tooltip-scanning, because GameTooltip:SetLootItem / C_TooltipInfo.GetLootItem do seem to show an accurately scaled item.
