Removed old script unit tests (#600)

Removed unit tests related to the old script, `cdash_analyze_and_report_random_failures.py`.
These tests will be put back as unittests for the module file `CDashAnalyzeReportRandomFailures.py`.

This change will keep `cdash_analyze_and_report_random_failures_UnitTests.py` focused on
the system tests for how the class `CDashAnalyzeReportRandomFailuresDriver` is used.
