Merge #12438: [Tests] Fix trivial typo in test_runner.py causing error

ada1af6 Fix typo in test_runner.py causing error (MeshCollider)

Pull request description:

  In the case that a test fails, the typo in run_tests() (introduced in #11858) will cause an error rather than printing out the combined logs, hiding the cause of the failure.
