Re-use baked project for all tests

[bouweandela]

Description

Speed up the tests by re-using the baked project.

Also:

• replace the deprecated .project with .project_path
• fix the API docs test where the output has changed a bit
• use --no-autodetect when running prospector to avoid a warning about Django not being installed

Awesome! Will merge this after #347. The doc test was also fixed in that PR, so let's take that fix out of this PR.

[egpbos]

I rebased on main and removed the test fixes from the second commit. That left only the deprecated .project replacement, so I renamed the commit to reflect that. This resolves the merge conflicts.

[egpbos]

Ok, fun! Two errors detected :)

1. Since we now generate one folder from the different tests and ruff runs on the combined end result of the other tests, which includes some generated sub-modules that don't pass ruff, it now fails on those. Solution: remove the __init__.py files from those sub-modules (ruff complains about them because they don't end in a newline), since with modern namespace sub-modules they are not even necessary anymore.
2. The test fix from main doesn't work either anymore, because the ASCII table that is generated now with those added sub-modules does not match the ones that we got before. We should modify those expected lines. The test does appear to be a bit fragile this way, so maybe including in those lines the variable number of spaces would be better. But for now, let's keep it simple.

[egpbos]

It seems like __init__.py is still necessary at this point, possibly the configuration isn't yet properly set for new style namespace packages. Anyway, no problem, fix coming.

[egpbos]

Did a fixup rebase of the first commit to fix the tests there.

[egpbos]

Thanks a lot for this!

Thanks for fixing the merge conflict @egpbos!
