Add @coversNothing annotation to prevent raising risky warnings in PHPUnit 9.2

[emodric]

PHPUnit added a warning when a test method is missing @covers* annotation and one is using forceCoversAnnotation config: sebastianbergmann/phpunit#4246 .

Running the tests on PHPUnit 9.2 without this results in:

33) App\MyCompilerPass::compilation_should_not_fail_with_empty_container
This test does not have a @covers annotation but is expected to have one

Since this test method is final, we cannot override it in our project, so this is the best way to fix this.
