possibly non-deterministic test juju.unit.tests.test_lifecycle.UnitRelationLifecycleTest.test_join_hook_error

[Clint Byrum]

Have seen this test fail (on natty) a few times and then succeed later:

[FAIL]
Traceback (most recent call last):

    self.assertEqual(len(errors), 1)

I've looked over this test to verify its correctness and race free, and run it
10k times on precise without error.

It only seems to fail on Natty, and actually I misspoke, it has not succeeded on Natty, hence the PPA being out of date.

From recent 0.5 ppa build, precise worked, oneiric and quantal failed with this error and some other hook related issues.
