  rewrite author order test
  **Description of the bug**
  This test fails occasionally. Rewrite it removing 2 assertions:
  [https://github.com/hydroshare/hydroshare/blob/4372-communities-and-groups-2.0/hs_c[…]ore/tests/api/native/test_reorder_authors_management_command.py](https://github.com/hydroshare/hydroshare/blob/4372-communities-and-groups-2.0/hs_core/tests/api/native/test_reorder_authors_management_command.py#L180)
  
  [https://github.com/hydroshare/hydroshare/blob/4372-communities-and-groups-2.0/hs_c[…]ore/tests/api/native/test_reorder_authors_management_command.py](https://github.com/hydroshare/hydroshare/blob/4372-communities-and-groups-2.0/hs_core/tests/api/native/test_reorder_authors_management_command.py#L152)
  
  Also: rewrite this management command so that it takes a res ID as a param:
  https://github.com/hydroshare/hydroshare/blob/4372-communities-and-groups-2.0/hs_core/management/commands/reorder_authors.py#L24
  
  Steps to reproduce the bug:
  http://ci.hydroshare.org:8080/job/hydroshare-pull-requests/5750/testReport/junit/hs_core.tests.api.native.test_reorder_authors_management_command/TestReorderAuthorsCommand/test_command_fixes_triplicate_authors/
  
  **Expected behavior**
  Test should not be dependent on django .get() order
