setUp being called twice is not an error

[Robert Collins]

But like bug 508200 this indicates broken user code.
E.g.
>>> class T(testtools.TestCase):
... def setUp(self):
... super(T, self).setUp()
... super(T, self).setUp()
... def test_foo(self):
... pass
...
>>> T('test_foo')()
<testtools.testresult.real.ExtendedToOriginalDecorator object at 0x16cff10>
>>>

I hit this problem again today in a round-about-way; due to logging setup done in setUp() logger calls started to disappear only after the second call. This would have saved a fair bit of debugging

https://github.com/testing-cabal/testtools/pull/90 should indeed fix it.

Fixed in a prior release.
