tests: stabilize `test-http-bad-server.t` on macOS

I'm not sure what's going on here, because I got one test run where this worked,
but two where it gave this error instead.  It's connection related as the
comment says it should be, so good enough.

This test cover a bug that no longer exist.

Define helpers.

  $ hg_log () { hg log -G -T "{rev}:{node|short}"; }
  $ commit () { echo "foo - ${2:-$1}" > $1; hg commit -Aqm "Edited $1"; }
  $ strip() { hg --config extensions.strip= strip -q -r "$1" ; }

Setup hg repo.

  $ hg init repo
  $ cd repo
  $ touch x; hg add x; hg commit -m "initial"
  $ hg clone -q . ../clone
  $ commit a

  $ cd ../clone

  $ commit b

  $ hg pull -q ../repo

  $ ls -1 .hg/cache/branch?*
  .hg/cache/branch2-base
  .hg/cache/branch2-served
  $ cat .hg/cache/branch?-served

  $ strip '1:'

After the strip the "served" cache is now identical to the "base" one, and the
older one have been actively deleted.

  $ ls -1 .hg/cache/branch?*
  .hg/cache/branch2-base
  $ cat .hg/cache/branch?-base
  7ab0a3bd758a58b9f79557ce708533e627776cce 0
  7ab0a3bd758a58b9f79557ce708533e627776cce o default

We do a new commit and we get a new valid branchmap for the served version

  $ commit c
  $ ls -1 .hg/cache/branch?*
  .hg/cache/branch2-base
  .hg/cache/branch2-served
  $ cat .hg/cache/branch?-served
  a1602b357cfca067600406eb19060c7128804d72 1
  a1602b357cfca067600406eb19060c7128804d72 o default


On pull we end up with the same tip, and so wrongly reuse the invalid cache and crash.

  $ hg pull ../repo --quiet
  $ hg heads -T '{rev} {node} {branch}\n'
