test_uninstall_application randomly fails with CPO error

[Richard Huddie]

test_uninstall_application randomly fails with the following error:

Traceback (most recent call last):
File "/home/phablet/dev/fix/ubuntu_sanity_tests/tests/test_uninstall_application.py", line 61, in test_uninstall_application
self.assertIn('simpleclick', apps_scope.get_applications('local'))
File "/usr/lib/python3/dist-packages/autopilot/introspection/dbus.py", line 416, in getattr
(self.class.name, name))
AttributeError: Class 'GenericScopeView' has no attribute 'get_applications'.

Most of the time the test works correctly, but this error sometimes makes it incorrectly fail.

The get_applications method is defined in the helper class, so for some reason it is randomly failing to inherit this method.

Should we call out a specific test here? It seems like a general issue with GenericScopeView. I've also seen such traceback as:

Traceback (most recent call last):
