clfilter: fix a false positive in the test-obsolete.t

We push between two repo which once filtered looks unrelated. Weakness in the
current implementation allows this push to be done without -f. But later
improvement with filtering will make this push fails for unrelatedness. However
we want this push to fail for including bumped changeset. So we had a smaller
push --force to make them related.
