REVISION SUMMARY
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.
