Restrict test classes to the development autoload

[greg0ire]

I am targetting this branch, because there is a BC-break : people might extend our test classes, who knows?

Changelog

### Removed
- Test classes autoload is no longer available when not in development

Subject

This PR restricts the autoload to test classes.

Would be great to do a grep of Sonata\Cache\Tests usage from all sonata projects and put the result here as a remember.

We should rename the test directory to Tests, because the Test directory should only contain all abstract test cases for other developers.

You're talking about bundle repositories using the "old" directory structure.

Here, public test cases would be under src/Test and test classes under test.

Those folders are not part of the namespace thanks to PSR-4.

Sorry, you're absolutely right. Didn't think about that.

Could you please rebase your PR and fix merge conflicts?

[core23]

Should we merge this in the stable branch @Soullivaneuh ?

Same as https://github.com/sonata-project/ecommerce/pull/384

[soullivaneuh]

If no test internal dependencies, yes.

Please create a new PR for the stable branch @greg0ire
