Do not return the stat since we don't know the resulting the size that the file will have after having all transformations applied. When including files, PHP 7.4 and newer are sensitive to file size reported by stat.

if the fixture is recently created and it has no content, the parser returns null to $recording. And array-like access to null via $recording[0] will raise an exception. With this little check this behavior is fixed and also all tests will work properly.
