chore: Minor test fixes (#211)

* chore(ci): Silence fs.Stats ctor deprecation warning

Do this in the worst way possible because stuff depends on it being an
instance of fs.Stats with the right prototype, but also there's no
supported way to mock create an object of that type... so __proto__
hackery will have to suffice 😬

* chore(ci): Safer temp dir for testing

This should ensure that the directory is always cleaned up after tests
run.
