Fix some test data (#2770)

## Summary:

Ben made me rethink my approach. Maybe we shouldn't be migrating in `renderQuestion`, maybe we just need to be better about typing our test data?

~~While working on answerless rendering, I noticed some test failures related to calling `splitPerseusItem` (which itself calls `parseAndMigratePerseusItem`). It occurred to me that our test helper `renderQuestion` isn't calling the migration function before passing the PerseusItem to ServerItemRenderer; since ServerItemRenderer doesn't upgrade PerseusItems anymore, that's a problem!~~

~~This fixes `renderQuestion` in `packages/perseus/src/__tests__/test-utils.tsx` (and tests that needed to be updated as a result) but doesn't fix `renderQuestion` in `packages/perseus/src/widgets/__testutils__/renderQuestion.tsx`. That's because that version of `renderQuestion` takes a PerseusRenderer and not a PerseusItem which I don't think our upgrade script handles. While this further strengthens my belief that Renderer should be internal to Perseus (with ServerItemRenderer or ArticleRenderer being the mount for all Perseus rendering), it doesn't change the fact that we have a lot of tests that are currently rendering directly to a Renderer.~~
