The verbose output shown on bots didn't print the first failing result
of a flaky test before. Now the result line shows all results and
the details in the end show the output of the first failure.

Previously it was confusing as it seemed that the json results and
the test runner output differed.

We now print PASS in all caps like the other statuses. A test for
this case already existed and the output is now updated.
