rebase --keep-base: imply --reapply-cherry-picks
As --keep-base does not rebase the branch it is confusing if it
removes commits that have been cherry-picked to the upstream branch.
As --reapply-cherry-picks is not supported by the "apply" backend this
commit ensures that cherry-picks are reapplied by forcing the upstream
commit to match the onto commit unless --no-reapply-cherry-picks is
given.
