clone: do not turn hidden changeset public on publishing clone (issue3935)

Before this changeset local clone of a repo with hidden changeset would include
then in the clone (why not) and turn them public (plain wrong). This happened
because the copy clone publish by dropping the phaseroot file entirely making
everything in the repo public (and therefore immune to obsolescence marker).

This changeset takes the simplest fix, we deny the copy clone in the case of hidden
changeset falling back to pull clone that will exclude them from the clone and
therefore not turning them public.

A smarter version of copy clone could be done, but I prefer to go for the
simplest solution first.
