Rename test action to avoid AbstractController::dispatchMessage collision

Symfony 5.4 and 6.4 ship AbstractController::dispatchMessage(object $message,
array $stamps = []): Envelope. The Messenger test action declared an
incompatible override (dispatchMessage(MessageBusInterface): Response), which is
fatal on those versions and only passed locally because newer Symfony dropped
that parent method. Rename the action to dispatchTestMessage; the route is
unchanged (/dispatch-message).
