(Issue3303)
Check that remote secret changeset are ignore when checking creation of remote heads

We add a secret head into the push destination. This secret head shadows a
visible shared between the initial repo and the push destination.

  $ hg up -q 4 # B'
  $ mkcommit Z --config phases.new-commit=secret
  test-debug-phase: new rev 5:  x -> 2
  test-hook-close-phase: 2713879da13d6eea1ff22b442a5a87cb31a7ce6a:   -> secret
  $ hg phase .
  5: secret

We now try to push a new public changeset that descend from the common public
head shadowed by the remote secret head.

  $ cd ../initialrepo
  $ hg up -q 6 #B'
  $ mkcommit I
  test-debug-phase: new rev 8:  x -> 1
  created new head
