Update review tests after tidy up work

https://eaflood.atlassian.net/browse/WATER-4739

For a detailed explanation of the tidy-up work, see [Tidy up two-part tariff review code and routes](DEFRA/water-abstraction-system#1443). In short, 12 months after starting the work, knowing what we know now, we'd have structured the code differently.

That's tidy up work has affected some of the view, which means some of the tests are failing because they can no longer identify the elements to select. This change updates the review tests to get them working again.
