test-http-bad-server: use the new pattern-reading for a test-case

This test case is now less sensitive to change of unrelated bits of the
client/server exchange.

Since this introduce some churn in the output, we do it independently for each
test cases. This patch is the last of such changes, for both sent and recv
cases.
