detect module if the controller is defined with alias

If the controller is defined in this way:
controllers' => array (
    'invokables' => array (
      'test' => 'Test\Controller\TestController',
));
then $MvcEvent->getRouteMatch()->getParam('controller') will return 'test' instead of 'Test\Controller\TestController'.

In this case module name can't be detected using explode by '\\' cause will end in an error moduleName = controllerName (cause controller does not contain any '\\')

NB: maybe is not the cleaner solution but can be a start point and it works :)
