Change the way we test snapshots

This is something that is not working after the upgrade to
`react-scripts`, and also has the benefit of generating more correct and
less brittle snapshots.

The other option is adding [a proper serializer][1] like
[enzyme-to-json][2], but this option also makes things easier to
understand without adding another dependency.
