This tests needs the _require_fail_make_request helper from
common/fail_make_request, so include that file to avoid a test failure.

Use the helpers from common/fail_make_request instead of open coding
them. This switches to using a higher error count than the existing
code, which was the intention from the very beginning (and doesn't
actuallt matter for the short sequences in this test).
