httppeer: avoid another bad reference before assignment warning

This wasn't a problem, because `b''` from the `AttributeError` handler is in
`bundle2.bundletypes`, so the following loop and conditional always run at least
once.  But PyCharm can't figure that out on its own, and it took a little
exploring to figure out it wasn't a problem.  The usage in `bundle2.writebundle`
is to look it up in the map of bundle types, so it will break in a more obvious
way in the unlikely event that the empty string is removed from the map in the
future.

Test generation through the dedicated command
=============================================

  $ cat >> ../server/.hg/hgrc << EOF
  > [clone-bundles]
  > auto-generate.on-change = no
  > EOF

Check the command can generate content when needed
--------------------------------------------------

Do a push that makes the condition fulfilled,
Yet it should not automatically generate a bundle with
"auto-generate.on-change" not set.

  $ touch quoi
  $ hg -q commit -A -m 'add quoi'

  $ pre_push_manifest=`cat ../server/.hg/clonebundles.manifest|f --sha256 | sed 's/.*=//' | cat`
  $ pre_push_upload=`ls -1 ../final-upload|f --sha256 | sed 's/.*=//' | cat`

  $ ls -1 ../server/.hg/tmp-bundles
  $ test "$pre_push_manifest" = "$post_push_manifest"
  $ test "$pre_push_upload" = "$post_push_upload"

Running the command should detect the stale bundles, and do the full automatic
generation logic.

Test modification of configuration
==================================

Testing that later runs adapt to configuration changes even if the repository is
unchanged.

adding more formats
-------------------

bundle for added formats should be generated

change configuration

  $ cat >> ../server/.hg/hgrc << EOF
  > [clone-bundles]
  > auto-generate.formats = v1, v2
  > EOF

refresh the bundles

  $ hg -R ../server/ admin::clone-bundles-refresh

the bundle for the "new" format should have been added

Changing the ratio to something that would have triggered a bundle during the last push.

  $ cat >> ../server/.hg/hgrc << EOF
