[GitHub] any23 issue #49: ANY23-314 Service fails to return extraction in case of ext...

    In the case where one encounters a parse and/or extraction error hence an unsuccessful extraction, one would see the following result. 
    As you can see, the partial extraction is now included at the bottom of the servlet response which is much better e.g. more forgiving, than a plain stack trace and error message.
    ```
    Failed to fully parse input. The extraction result, at the bottom of this response, if any, will contain extractions only up until the extraction error.
