Tests often fail with a traceback that looks like this:
---
Traceback (most recent call last):

super(TestSimplePage, self).setUp()

But most of the lines in that traceback aren't useful to the test author. Instead, we should investigate whether we can do something like this:
---
Traceback (most recent call last):
File "/home/phablet/autopilot/ubuntu_calculator_app/tests/test_simple_page.py", line 32, in setUp
super(TestSimplePage, self).setUp()
File "/home/phablet/autopilot/ubuntu_calculator_app/tests/__init__.py", line 57, in setUp

We can probably do this by setting '__unittest = True' in internal modules. We need to do this carefully though, since we still want to show enough information to debug the problem...
