fix(event-dispatcher): un-ignore test_dispatcher_support_for_additional_args

The only missing seam was the PHP test's
ReflectionMethod(getPhpExecCommand) access; add the test-only
__get_php_exec_command wrapper and port the test on the existing
get_listeners override and process-executor mock infrastructure.
