Not expected values ​​in onValuesChange method.

[tippillow]

I am using Form.List inside Form.List and when removing the inner formList onValuesChange() is giving away an unexpected second argument. form.getFieldsValue() returns the same. But if you call the onFinish() method, then it is correct the value I expected.
