fix(CVEvaluator): `clone` the estimator before use #249

Whoops, somehow the estimator wasn't getting cloned before being CVFitted on. This wasn't caught by the tests as the default model we used could be warm-started and refit without issue. I ran across this bug while using this on an MLPClassifier.
