topicidx: stop assigning index number to obsolete changesets

Obsolete changeset are no longer part of the stack, the old logic tried to
assigns them the index of their successors but this is flacky and error prone.
So we stop doing so.

Testing `hg stack` on complex cases when we have multiple successors because of
divergence, split etc.
