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.

Differential Revision: https://phab.mercurial-scm.org/D12073

This test file aims at test topological iteration and the various configuration it can has.

  $ cat >> $HGRCPATH << EOF
  > [command-templates]
  > log={rev}\n
  > EOF

On this simple example, all topological branch are displayed in turn until we
can finally display 0. this implies skipping from 8 to 3 and coming back to 7
later.
