Bug-fix: Log data supports array value

As-is: When log data contains array, it saves only last element of the
array.
  for (const auto& v: in_uids) _log_input_args["in_uids"] = Json::Value(v);
To-be: It saves every element of the array
  _log_input_args["in_uids"] = Json::Value(Json::arrayValue);
  for (const auto& v: in_uids) _log_input_args["in_uids"].append(Json::Value(v));
