[PATCH 2/4] tests/functional: avoid duplicate messages on failures

["Daniel P. Berrangé" <berrange@redhat.com>]

In some scenarios the same tests is mentioned in both the
'res.results.errors' and 'res.results.failures' array returned
by unittest.main(). This was seen when the 'tearDown' method
raised an exception.

In such a case, we printed out the same information about where
to find a log file twice for each test. Track which tests we
have already reported on, to avoid the duplication.
