Move tests to the repository root level

I don't thing there's any need to bundle them in the built package. Smaller package sizes == happier devs and planet.

Dev reference: https://hynek.me/articles/testing-packaging/ | https://blog.ionelmc.ro/2014/05/25/python-packaging/#the-structure

Project structure:

src/
╰─ project_name/
   ╰─ ...
tests/
╰─ ...

<configuration files etc>

This sounds good to me!

Don't forget to update https://github.com/wagtail/cookiecutter-wagtail-package/blob/main/wagtail-%7B%7B%20cookiecutter.project_name_kebab%20%7D%7D/setup.py#L23 to prevent the tests folder being packaged up an installed as a global "tests" app (which might conflict with the test suite of draftjs_exporter which does this).

yep, that's what we do on wagtailmedia - https://github.com/torchbox/wagtailmedia/blob/main/setup.py#L37-L38

Test were moved to the root level. Now to move package_name to src/package_name so it is never a top level import
