adaptavist.get_test_results() can't sort by 'index'

[KanoB]

Hello,

For some reason our adaptavist plugin in our server JIRA instance does not return index key in the get_test_results endpoint "{self._adaptavist_api_url}/testrun/{test_run_key}/testresults"

So, when sort is attempted in newer version of adaptavist plugin (> 2.0.0) it fails because index key does not exist result["scriptResults"] = sorted(result["scriptResults"], key=lambda result: result["index"])

` def get_test_results(self, test_run_key: str) -> List[Dict[str, Any]]: """ Get all test results for a given test run.

      :param test_run_key: Test run key of the result to be updated. ex. "JQA-R1234"
      :returns: Test results
      """
      request_url = f"{self._adaptavist_api_url}/testrun/{test_run_key}/testresults"
      self._logger.debug("Getting all test results for run %s", test_run_key)
      request = self._get(request_url)
      if not request:
          return []
      results = request.json()

      for result in results:
          result["scriptResults"] = sorted(result["scriptResults"], key=lambda result: result["index"])
      return results
