Generic Extractor update

We have fixed an error in handling recursive calls in the new Generic extractor.

If you had a working configuration which uses recursions - by using the children parameter for a job (see https://github.com/keboola/generic-extractor#jobs), the format of result data and the parent ID column might have changed, which could result in a failed import to Storage API.

Please let us know if such error affects you and we'll take care of it!
