Testrail report script fails if docstring is null

[Alexander Kurenyshev]

When we have cases with an empty docstring test rail report uploading tool fails with:
Traceback (most recent call last):
  File "fuelweb_test/testrail/upload_cases_description.py", line 441, in <module>
    main()
  File "fuelweb_test/testrail/upload_cases_description.py", line 432, in main
    default_test_priority=testrail_default_test_priority
  File "fuelweb_test/testrail/upload_cases_description.py", line 70, in get_tests_descriptions
    title, steps, duration = _parse_docstring(docstring, case)
  File "fuelweb_test/testrail/upload_cases_description.py", line 266, in _parse_docstring
    title = _parse_title(title_r, case) if title_r else ''
  File "fuelweb_test/testrail/upload_cases_description.py", line 291, in _parse_title
    title = ' '.join(map(string.strip, s.split('\n')))
