Consecutive call of `canMakePayment()` is restricted and second call always returns exception.

What steps will reproduce the problem?
(1) Go to https://output.jsbin.com/savated
(2) Press "Start"

Find the code here: http://jsbin.com/savated/edit?html,js

What is the expected result?
To see "available" or "not available" on both "Credit" and "Prepaid".

What happens instead?
"Prepaid" always "exception"

I'm expecting cases where a developer wants to use multiple different set of payment request instances to enable different set of branded buttons. In order to determine if showing those branded buttons, calling `canMakeyPayment` would be the best practice, but this limitation prevents to do it.

I'd like this restriction to be relaxed.
