This adds tests that ensure all the data generated by
ReviewRequestPageData is what we'd expect, and that te entries
behave/render correctly.

These tests caught a couple of small issues with status updates (both
data collecting and rendering with URLs without URL text, which have
been fixed in this change.

Unit tests pass.
