Re: [w3c/payment-request] Define handling of multiple applicable modifiers (#684)

Not sure how I didn't find #309 in my search… It looks like duplicate PMIs were disallowed while working on #581 (which I don't think is a good solution and it seemed others agree) but that text was removed in https://github.com/w3c/payment-request/pull/581/commits/5e6ca6da68bd65634a309662c067c3b83eed97fc before merging. It seems like #581 then didn't end up addressing the issue.

There was some talk about having the first match win but I'll note that shippingOptions work in the opposite way… the last `selected` wins: 

> If more than one item in the sequence has selected set to true, then the user agent selects the last one in the sequence. 

I think we should be consistent on first vs. last in tie breaker scenarios.
