Check if addon has an __init__.py

Fix #15

Because creating a test module is not as trivial as it was before (it needs a valid manifest and an init file), I created a fixture to create modules for the test of Addon.

A step further would be to also refactor test/common.py:populate_addons_dir to be a fixture too.

Looks good, thanks for the contrib.

Could you add a file named news/25.feature with a short changelog entry in reStructuredText format (or plain text) ?
