Ensure access_token are removed

When we remove the client, we should ensure that access_token are also removed.

To ensure that, I created a test that generated an access_token. So when we remove the client, this association should be cascaded and shouldn’t generate an error.

Also I moved some Api related stuff to the ApiBundle (like the developer controler and ClientType form)

app/config/routing.yml
