Title: Optimal Payments: submit region instead of state when billing address is not CA or US

I got an email from the guys at Optimal requesting this change. When the address is CA or US they look at the state xml tag, otherwise they look at the region.

Remote test added which uncovered the issue, code changes fixed the failing test.
