fix TestRunnerViewPart.prepareLaunchConfigForRelaunch() to strip the failed first part of a message as we are just rerunning
also set the ATTR_FAILURES_NAMES to null instead of empty string so when we do failed first again we will create the proper message and do not add the Rerun to start of message as we do this inconsistently (only added after a failed run then rerun)
fixes #1434
What it does
Fixes the console message for a rerun to not have trailing info about failed tests first and makes the message more consistent by not adding Rerun to start of message some times and others not.
