Group middleware is duplicated

[Pumpuli]

Group middleware is added to the middleware stack twice and thus executed twice.

The problem areas seem to be:

1. When adding routes inside a group (RouteGroup#map()), the group's middleware is added to each route:

2. When dispatching, the middleware stack is populated from both the route and its group (Dispatcher#setFoundMiddleware()), but since route already contains group middleware, the group middleware gets added a second time:
