rewind: always compute successorsmap

We have had access to rewind targets (predecessors) in this function before,
but having access to current successors (in the form of successorsmap) is also
useful and will be used in following patches.

We're emptying successorsmap when --as-divergence is given to keep the current
behavior. It's done before using it for --dry-run and actual work.

Check that evolve shows error while handling split commits
