Improve testing

[fdemmer]

The latest release broke a documented feature.

Regardless of how this situation will be solved, I propose to improve automated testing. Here are some of my suggested changes.

It includes a currently @unittest.skip() marked test (FormTests.test_form_condition_callable) which leads to a RecursionError due to using get_cleaned_data_for_step in a condition_dict callback.

This could probably be split up so it could be merged more easily.

I'm bound to have missed bits, but for instance there are improvements to tests on -

• Cookies
• File Uploads

If you make these separate PRs they can go in on their own + will be easier for others to evaluate; I haven't gone though the commits, but it may be you can create new PRs and cherry pick the relevant commits.

We may even want to split things up a bit in the test class, rather than having one large one.

I guess anyone can make this go forward by creating distinct and reviewable PRs (keeping original author ownership, of course).
