transaction: remember original len(repo) instead of tracking added revs (API)

It's silly to keep updating xrange(len(changelog), len(changelog) + 1) for
each added revision. Instead, let's simply remember the first revision to
be added.

The test output slightly changed as the branch cache is also warmed up by
stream clone, which seems more consistent.

.. api::

   ``tr.changes['revs']`` is replaced by ``tr.changes['origrepolen']`` which
   is the first revision number to be added.
