This fixes the output by removing the line which said just "error:", which would appear when the worktree is dirtied while editing the initial rebase todo file. This was introduced by 97e1873 (rebase -i: rewrite complete_action() in C, 2018-08-28), which did a somewhat inaccurate conversion from shell. To avoid that such bugs re-appear, test for the condition in require_clean_work_tree().
