As of PHP 8.1, passing null to not explicitly nullable scalar parameters for PHP native functions is deprecated.
In this case, $class within applyWildcard() may be null, which leads to the following deprecation notice as can be seen when running the tests on PHP 8.1:
Deprecated: class_exists(): Passing null to parameter #1 ($class) of type string is deprecated in path/to/patchwork/src/CallRerouting.php on line 141
By handling null separately in the condition, the previous behaviour is maintained.
