Merge #652: Fix duplicate rustsec issue creation

2fecab1 Fix duplicate rustsec issue creation (Jamil Lambert, PhD)

Pull request description:

  When the audit runs on all 3 lockfiles at the same time a problem in multiple lockfiles can result in multiple issues being created for the same RustSec ID.

  Run the jobs one at a time so that issues created are seen by the next jobs and no duplicate issue is created.
