interrupted tests apparently lead to success

Consider this test case from workflow:

14:33:58 tests.bb_run_test DetermineBuildbotTestCase.test_given_valid_buildbot_in_keys ... Invalid buildbot "t" (normalized to 't')- aborting.
14:33:58 INTERRUPTED in 0.00s
14:33:58 
14:33:58 ========================================================================
14:33:58 FAILURES
14:33:58 None!
14:33:58 
14:33:58 FAILED.  22 tests / 5 cases: 21 passed, 0 failed.  (Total test time 0.03s)

Jenkins think this suite passed because Testify returns code 0, but obviously that is not correct. At minimum, we need to correctly report this as an error.

It may also be worth looking at the status string "FAILED. 22 tests / 5 cases: 21 passed, 0 failed." since it contains several lies.

Still a bug afaict:

$ cat test2.py
import testify as T

class F(T.TestCase):
    def test(self):
        raise KeyboardInterrupt
$ testify test2.py
-
FAILED.  1 test / 1 case: 0 passed, 0 failed.  (Total test time 0.00s)
$ echo $?
0
