revision traversal: --remove-empty fix (take #2).

Browse Source 
Marco Costalba reports that --remove-empty omits the commit that
created paths we are interested in.  try_to_simplify_commit()
logic was dropping a parent we introduced those paths against,
which I think is not what we meant.  Instead, this makes such
parent parentless.
