router.match doesn't work with delegates anymore

[wilzbach]

Worked fine in 0.7.31, but broke in v0.8.0:

#!/usr/bin/env dub
/+ dub.sdl:
name "hello_vibed"
dependency "vibe-d" version="~>0.8.0"
+/
void main()
{
    import vibe.d;
    auto settings = new HTTPServerSettings;
    settings.port = 8080;
    auto router = new URLRouter;
    router.match(HTTPMethod.HEAD, "aa", (req, res) {
        res.writeBody("Hello, World: " ~ req.path);
    });
    listenHTTP(settings, router);
    runApplication();
}

Will prepare a PR soon.
