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
could this be brittle?
very specific css and equality on the value
`have_content value` maybe more forgiving than `eq value`
as for specific css there is a trade off either way brittle versus catching more errors and I'm not sure of the best approach
