Fix check if `instanceof RouteMatch` (detected via static analysis)

[TysonAndre]

This check was always false. The old check was searching for \Zend\Mvc\Console\Service\RouteMatch, which doesn't exist.

setRouteMatch accepts \Zend\Router\RouteMatch or the legacy subclass:

The possibilities (From the Zend\View\Helper\Url code):

// MVC router extends RouteMatch.
use Zend\Mvc\Router\RouteMatch as LegacyRouteMatch;
use Zend\Router\RouteMatch;

Note: There were no unit tests of this case. Existing unit tests pass.

Still requires a test case addition

I've added a unit test at this time.
