Migrating usages of old domain object to new IDomainService, this also involves updated quite a lot of unit tests. I've updated quite a few of the routing tests to be pure mocking tests which works much nicer than before so there's no db access, this also means they run a million times faster (need to clean them up further still though). Still more tests failing which need fixing.
