Fix status in orphan feature

No PT/Jira story

- fix incorrect references to OrphanStatus/OrphanSponsorshipStatus in orphan.feature
- remove references to 'Sponsored'/'Unsponsored' as these belong to OrphanSponsorshipStatus and are never set manually
- add tests for fields in index view
As I said with css there is no wrong and right answer I was just highlighting the trade off that we are making.
As for the have content issue a simple format change such as adding currency or other types of formatting would break adequate tests needlessly. For the things where we need to make a stronger distinction could we just not use ^Active$ or something similar for the value expected?
