If someone send a malformated client_id when trying to authenticate using the API we got a 500 if wallabag use postgres because the request send a string instead of an integer.
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)
