phases: do not exchange secret changesets
Any secret changesets will be excluded from pull and push. Phase data are
properly synchronized on pull and push if a changeset is seen as secret locally
but is non-secret remote side.
This patch does not handle the case of a changeset secret on remote but known
locally.
