Delete two committed tool transcripts holding this branch red

x/npm-test.log and x/typecheck.log are tracked leftovers from the
git add -A sweep in #785 (pre-dating the repo-scratch-hygiene test
added by #786). master already carries this fix via #853; this
branch forked before that landed, so it inherited the red test
separately. Same fix, scoped to the same two paths.
