JavaScript shouldn't garbage-collect PaymentRequest when it still has
promises in flight. Initially, only accept_resolver_ (for show),
retry_resolver_ and complete_resolver_ blocks the GC, this patch adds
the following resolvers to the list:
* has_enrolled_instrument_resolver_
* can_make_payment_resolver_
* abort_resolver_
