Standardise default country and state

The OFN software was first written in Melbourne and a lot of spec code
relies on the state Victoria being in the database. When we imported
Spree code, it came with its default state Alabame in the USA. Having
two different defaults is confusing and caused specs to fail in rare
circumstances. Let's standardise it here which will also open the path
to removing the seeding of test data and the exclusion of states and
countries in the database cleaner.
