    No json_object_put() for the json_obj created by json_object_object_get_ex().

    It is stated in the json_object.h from version 0.11:
    https://github.com/json-c/json-c/blob/json-c-0.11/json_object.h#L271

    As on json-c 0.11, there's no assert to check for the ref_count, we wont get
      crashed. But on json-c 0.13.1 (latest release), json_object_put will check
      for the ref_count first, so mtcAgent will crash.

    Test Done:
    Run mtcAgent with json-c version 0.13.1 with this patch, no crash found.
