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.

  $ hg init repo0
  $ cd repo0

Command works on an empty repo

  $ hg show work

Single draft changeset shown

  $ echo 0 > foo
  $ hg -q commit -A -m 'commit 0'

  $ hg show work
  @  9f171 commit 0

Even when it isn't the wdir

  $ hg -q up null

  $ hg show work
  o  9f171 commit 0

Single changeset is still there when public because it is a head

  $ hg phase --public -r 0
  $ hg show work
  o  9f171 commit 0

A draft child will show both it and public parent

  $ hg -q up 0
  $ echo 1 > foo
  $ hg commit -m 'commit 1'

  $ hg show work
  @  181cc commit 1
  o  9f171 commit 0

Multiple draft children will be shown

  $ echo 2 > foo
  $ hg commit -m 'commit 2'

  $ hg show work
  @  128c8 commit 2
  o  181cc commit 1
  o  9f171 commit 0

Bumping first draft changeset to public will hide its parent

  $ hg phase --public -r 1
  $ hg show work
  @  128c8 commit 2
  o  181cc commit 1
  |
  ~

Multiple DAG heads will be shown

  $ hg -q up -r 1
  $ echo 3 > foo
  $ hg commit -m 'commit 3'
  created new head

  $ hg show work
  @  f0abc commit 3
  | o  128c8 commit 2
  |/
  o  181cc commit 1
  |
  ~

Even when wdir is something else

  $ hg -q up null

  $ hg show work
  o  f0abc commit 3
  | o  128c8 commit 2
  |/
  o  181cc commit 1
  |
  ~

Draft child shows public head (multiple heads)

  $ hg -q up 0
  $ echo 4 > foo
  $ hg commit -m 'commit 4'
  created new head

  $ hg show work
  @  668ca commit 4
  | o  f0abc commit 3
  | | o  128c8 commit 2
  | |/
  | o  181cc commit 1
  |/
  o  9f171 commit 0
