Trial swallows errors in result objects

New submission from jml <[email protected]>:

The following script demonstrates that Trial doesn't report errors in test objects in any way.

{{{
#python
import unittest

from twisted.trial.unittest import TestCase


class BrokenResult(unittest.TestResult):

    def addFailure(self, test, failure):
        1/0


class FailingTest(TestCase):

    def test_foo(self):
        self.fail('No good reason')


if __name__ == '__main__':
    test = FailingTest('test_foo')
    result = BrokenResult()
    test.run(result)
    print result
}}}

If you run it, you'll see something like:

{{{
$ python swallow-error.py 
<__main__.BrokenResult run=1 errors=0 failures=0>
}}}

Instead, you should see some sort of error about the `1/0` line.
