Revert "maybe I'm doing the wrong thing by adding use lines for test modules"

Wow.  Even with the "fix" in, it runs correctly once, and then starts vomiting
with a similar error again as before the fix.  it'll fail 20 times in a
row, then pass 20 times in a row.  there's some haunted house level
shit going wrong here.

This reverts commit b121a061d8.
