Add 'Register a Birth' Smartdown flow (without content)
Update SmartDownScenarioTest
Due to the fact that 'country questions' are populated at build time and not anymore at render time,  stubbing countries within the Smartdown test framework would mean doing so after the tests will have already run and failed. It must be done before testing in order to populate the country drop-down list. Also, At the end of the process, countries must then be unstubbed in order to allow the rest of the Smart Answer tests to pass.
