evolve: always create commit when resolving divergence

When resolving content-divergence, the final commit we create may end
up empty (which means that Mercurial won't even create it). We've had
code for handling that in evolve ever since 41bf6c27a122 (evolve:
stabilize now handle conflicting changeset, 2012-08-23). However, that
resolved the issue by marking on the divergent commits as
successor. As Pierre-Yves has pointed out (in other code reviews), we
should instead be creating a new successor. So that's what this patch
does. It does that by setting `ui.allowemptycommit` while creating the
final commit. However, that is not enough, because we may end up
creating the same nodeid as already existed (we'd then end up trying
to mark the "new" commit a successor of itself). To solve that, we add
some salt to the commit extras. That salt affects lots of tests.
