graphmod: safer code when a changeset has two identical parents
While this situation should never under normal use, some real
life repos sometimes contain such changesets (older hg versions,
broken rebases, etc...)
hgweb was displaying an "Internal error" in this case, and graphlog
displayed a redundant branch all the way to null: it does not cost us
much to just ignore this extra parent when constructing the DAG.
