Manual tests

Note: this test requires that there is at at least one registered "visa" card. If the payment-sheet total's label displays "PASS", and the value US$12345, then a test has passed.

1. A modifier is applied by default to a card.
2. Missing PaymentDetailsModifier.data is same as passing default BasicCardRequest.
3. PaymentDetailsModifier.data with empty object is same as passing default BasicCardRequest.
4. A modified with a BasicCardRequest whose supportedNetworks is an empty array applies to all.
5. Given a set of modifiers, the last applicable "basic-card" wins.
6. Done!
