Routes are assumed to exist

Problem: Server will SEGV when no root route (\) is configured and no other route matches the request.

Expected behavior: Return 404 not found.

Reproduce: Use config below & request http://localhost:8080/.

Failing config:

[servers.alpha]
    host = 127.0.0.1
    port = 8080
    [servers.alpha.localhost]
        [servers.alpha.localhost.routes./www]
            type = normal
            path = www/
            methods = GET, POST, DELETE
            default_file = index.html

Output:
