Adjust hasItem function for QS-Inv

Apparently qs-inv reports two variables on the item data for how you have
`count` and `amount`
while other inventories appear to only have one of those

I'm assuming for compatibility sake

Apparently the `count` is updated differently, and `hasItem()` was checking for this first

I've swapped round the checks and appears to work better
