This PR makes `CoverageListenerTrait` pass with PHPUnit 9.3. It contains a backport of symfony#38054.

The problem that is addressed here is that a one of the fixture classes is now included in the output despite having a coverage of zero. The test now accepts both cases:

* The class is omitted from the output
* The class appears with 0.00% coverage.
