Title: Fix clean with for compatibility

### Spec Consideration

* `.clean_with` should run with given :only/:except options temporarily
* it means should not store given options
* to be compatible with DatabaseCleaner
* `.clean_with` should call `.clean` as standard behavior
* because DatabaseRewinder's `.clean_all` is optional
* and suggest adding `.clean_all_with` if needed
