precheck: fix false warning about divergence creation, in hg prune

In case of pruning with no successors, there is no chance for new divergence.
It was happening becuase current precheck logic assumes that every revision
being rewritten will be replaced with at least one successor.

Changes in test file demonstrate the fixed bug.
