emitter is always defined and it should stop script execution after emitting otherwise it tries to match more services.

For example:

$restapi->get('/ping', function() {
   return 'Pong';
});

// here we authorize - check for token
$restapi->authorize();

if I request service /ping, then it also tries to authorize, but it should stop script execution as soon as /ping service is matched and response is emitted.

there was a reason why "exit" wasn't here. I'm OK to add it for now but may need to remove in the future if i remember.
