Partially fix flaky tests (#308)

* Minor code style changes

* Disable rendering of timestamps in tests

* Update test snapshots

* Test everything with insta macros (no more `assert(_eq)?`)

- This has the benefit of creating snapshots for everything, allowing for later diffing

* Don't use `assert_debug_snapshot` for large string outputs

- This makes snapshots more human-inspectable

* Code style improvement on two tests

- `pause_by_space`
- `rearranged_by_tab`

* Minor code style improvements
