Merge #31: Run tests in a single thread, plus minor ci cleanups

a3ccd02 Run tests in a single thread, plus minor ci cleanups (Steve Myers)

Pull request description:

  I changed the CI tests to run in a single thread (one at a time) which should improve test reliability. I also added names to all the test tasks, and remove redundant clippy checks.
