rebase -r: do not write MERGE_HEAD unless needed
When we detect that a `merge` can be skipped because the merged commit
is already an ancestor of HEAD, we do not need to commit, therefore
writing the MERGE_HEAD file is useless.
It is actually worse than useless: a subsequent `git commit` will pick
it up and think that we want to merge that commit, still.
To avoid that, move the code that writes the MERGE_HEAD file to a
location where we already know that the `merge` cannot be skipped.
