evolve: abort when trying to move a node on top of itself

This provides a clearer error message when evolve misstakenly tries
to move a changeset on top of itself. Before we got an abort with a
cryptic message about trying to rebase a merge changeset.

A proper fix to make sure that evolve never tries to move a node on
top of itself will come in later patches.
