404 handled weirdly

So this is probably a thing with the router or something but I found this through the app generated by this lib so I thought I would start here ^^

My route config looks like
```js
app.route('/', require('./views/main'))
app.route('/title', require('./views/title'))
app.route('/test/:id', require('./views/test'))
app.route('*', require('./views/404'))
```
after adding 1 test route (with nothing special in it, just prints out the state)

Now when I add a button that does a pushState to `/test/4?a=4` that works great.
Then I reload the current page and I get `No route found for /test/1?a=4`.

I tried some stuff and saw that choo passes a default /404 route for, well, 404's :P which isn't there.
I would suspect it to go to `*` maybe but that doesn't seem the case.

Now when I add
```js
app.route('/404', require('./views/404'))
```
Everything seems to work, reloading on the state actually loads the right view.

I'll be glad to look into this more or give you more info if you need it
