exchange: don't attempt phase exchange if phase-heads was in bundle

The Mercurial core server doesn't yet include phase-heads parts in the
bundle, but our Google-internal server wants to do
that. Unfortunately, the usual exchange still happens even if
phase-heads part is included (including the short-circuited one for
old/publishing servers). That means that even if our server (again,
the Google-internal one, but also future Mercurial core servers)
includes a phase-heads part to indicate that some heads should be
drafts, that would still get overwritten by the phase updating that
happens after. So let's fix that by marking the phase step done if we
receive at least one phase-heads part in the bundle.

#require killdaemons

Tests discovery against servers without getbundle support:

  $ cat >> $HGRCPATH <<EOF
  > [ui]
  > logtemplate="{rev} {node|short}: {desc} {branches}\n"
  > EOF
  $ cp $HGRCPATH $HGRCPATH-withcap

  $ CAP="getbundle known changegroupsubset bundle2"
  $ . "$TESTDIR/notcapable"
  $ cp $HGRCPATH $HGRCPATH-nocap
  $ cp $HGRCPATH-withcap $HGRCPATH

Prep for test server without branchmap support

  $ CAP="branchmap"
  $ . "$TESTDIR/notcapable"
  $ cp $HGRCPATH $HGRCPATH-nocap-branchmap
  $ cp $HGRCPATH-withcap $HGRCPATH

Setup HTTP server control:

  $ remote=http://localhost:$HGPORT/
  $ export remote
  $ tstart() {

  >   echo 'push_ssl = false' >> $1/.hg/hgrc
  >   echo 'allow_push = *' >> $1/.hg/hgrc
  >   cp $HGRCPATH-nocap $HGRCPATH
  >   hg serve -R $1 -p $HGPORT -d --pid-file=hg.pid -E errors.log
  >   cat hg.pid >> $DAEMON_PIDS
  > }
  $ tstop() {
  >   killdaemons.py
  >   cp $HGRCPATH-withcap $HGRCPATH
