prune: add a test to demonstrate a bug

Test shows that pruning without any successor warns about creating
divergence which is not possible and is a false warning.

For the knowledge, this pattern of pruning (without any successor) an
already pruned cset is sometime used to keep successors locally but
vanish them at server side.

Tests running `hg evolve` with in-memory merge.
