Several middlewares executed with nested routes

[farwayer]

const nested = new Router()
  .get('/', (ctx, next) => {
    ctx.body = "root";
    console.log("root");
    return next();
  })
  .get('/test', (ctx, next) => {
    ctx.body = "test";
    console.log("test");
    return next();
  });

const router = new Router()
  .use(nested.routes());

GETting /test prints to console:

root
test

It is really unexpected behaviour!
Maybe related to #369 because the problem is with setting (.*) prefix in Router.use() function.

One more wrong thing with this behaviour: GETting /xxx will execute root although it should throw 404.

router.use('', nested.routes())

can be used as workaround.

This should be fixed in 7.4.0
