Avoid compiling and running tests twice

test-unit was building a second copy of the code with different features, and then the main test command ran the same tests anyway, so we just built and ran the tests twice

Locally shaves a minute off of a full build+test, on this branch (so both runs include the fsync change etc)

We're at [ 173.444s] overall for `just test` now
