Fix convert params and result in AdHocAction

 * Fixed wrong convertation of action params and result.
   In action parameters we can have an arbitrary dict, so
   this dict can contain lists, or other dicts. To convert
   params we should apply converter dict to base spec params
   and action result accordingly.
