tests: Fix some warnings in tests that popped up with newer python.

When running 'tox -e pylint' on a bionic system (python 3.6.4) I started
seeing errors today like:
  tests/cloud_tests/platforms/__init__.py:5: [E0401(import-error), ]
      Unable to import 'tests.cloud_tests.platforms.ec2'

The fix for those first errors was simply to create the __init__.py.
The second set of changes fixes fallout found from actually now having
pylint properly run on more of the cloud_tests.
