test-http-bad-server: move on test from bytes-count to pattern

test-http-bad-server: move on test from bytes-count to pattern

This specific test case is now using the new "close when a pattern is seen"
approach compared to the more fragile "that many bytes were sent" approach.

Since such change are still a bit noisy, we split each change in there own
changesets.
