copytrace: use the full copytracing method if only drafts are involved

This patch adds the functionality to use the full copytracing even if
`experimental.copytrace = heuristics` in cases when drafts are involved.

This is also a part of copytrace extension in fbext.

This also adds tests which are also taken from fbext.

.. feature::

   The `heuristics` option for `experimental.copytrace` performs full
   copytracing if both source and destination branches contains non-public
   changsets only.
