tests/functional: avoid duplicate messages on failures

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.
