clone: process 'lookup' return as an arbitrary symbol

In theory, checkout is expected to be a node here because it was returned by
peer.lookup.

In practice, multiple important extensions (like hg-git, hg-subversion) use
peers not backed by a mercurial repository where lookup cannot return a node.

Allowing arbitrary symbols is necessary to make these extensions working with
4.7.

We should probably introduce a new API in Core to have these extensions to
work without abusing the lookup API. In the meantime, a small change to
restore compatibility in 4.7 seems in order.

  $ hg init
  $ touch unknown

  $ touch a
  $ hg add a
  $ hg ci -m "1"

  $ touch b
  $ hg add b
  $ hg ci -m "2"

Should show unknown

  $ hg status
  ? unknown
  $ hg revert -r 0 --all
  removing b

Should show unknown and b removed

  $ hg status
  R b
  ? unknown

Should show a and unknown

  $ ls
  a
  unknown
