Subject: fix(event-dispatcher): un-ignore test_dispatcher_outputs_command

The ignore reason went stale: the getListeners override seam and a real
ProcessExecutor wired to the IO already cover the PHP setup, and IOStub
is the PHPUnit IOInterface-mock equivalent. IOStub now records
writeError calls (writeRaw was already recorded) so the
expects(once)->with(...) spies on writeError/writeRaw can be reproduced
as call-list equality assertions.
