Remove commented-out timeout_during_headers test. (#244)

We wound up with a second, working copy of this test at some point after
merging master into release-2.0.

-// TODO: Our current behavior is actually incorrect (we'll return BadHeader if a timeout occurs during headers).
-// However, the test failed to catch that fact, because get_and_expect_timeout only checks for error on into_string().
-// If someone was (correctly) checking for errors before calling into_string(), they would see BadHeader instead of Timeout.
