Don't clobber user's state/province in PaymentRequest address editor.

Before this patch, editing a shipping address with "California" state in
PaymentRequest UI on Android would result in "AA" selected in the state
dropdown. This is frustrating to the user and could result in delivery
errors on merchant side. The reason for this behavior is absence of
California-to-CA mapping logic, which prevents "CA" state from being
selected in the dropdown.

This patch checks whether the dropdown values list contains the state of
the shipping address. If there's no match, then the address editor uses
a text field for state instead of a dropdown. This is the same fallback
strategy that's used for the case of failure to download the list of
states/provinces for a country.

After this patch, editing a shipping address with "California" state
results in a text field being used for the state field. This text field
would contain the text "California".
