fix withdotkeys loosing ancestor keys on deep hashes #315

This fixes #231

The withdotkeys method is dropping the ancestor key after traversing two steps deep into a nested hash. This PR retains the full dotted-key hash path for the string so the desired fields for CSV download are included. Also updated the nested_has spec to test withdotkeys method on deep hashes.
