[Transform] Improve force stop robustness in case of an error (elasti…
…c#51072) If a transform config got lost (e.g. because the internal index disappeared) tasks could not be stopped using transform API. This change makes it possible to stop transforms without a config, meaning to remove the background task. In order to do so force must be set to true.
