The initial status updates entry on the review request page generally

will accompany the review request when first published, or will appear

shortly after as the result of a call to some external service or tool.

When first shown, it was appearing as new, with that state changing

shortly after when a status update changes. Showing this entry as new

doesn't really benefit anyone, and the jump in newness is a bit weird.

It also just wasn't useful as the newness never represented things like

new reviews from status updates.
This change forces the entry to never appear as new. Replises will

continue to appear as new as needed.

Unit tests pass.
Tested that the initial status update entry didn't appear new on

review request creation.
