evolve: fix the conflicts error message during content-divergence resolution

Before last patch, we didn't had an automated way to continue an interrupted
content-divergence resolution and we used to show a very long error message on
how to continue manually.

This patch replaces that long error message with nice small message which tells
how to continue and how to abort. We still show `hg update -C .` to abort as we
need to test and make `--abort` work in case of content-divergence.

Basic test of divergence: two divergent changesets with the same parents
With --all --any we dedupe the divergent and solve the divergence once
