While creating a new user using the API, we also create a new client for the current user.
So the app which just create the user can use its newly created client to configure the app.
That new client is only return after creating the user.
When calling the endpoint /api/user to get user information, the new client information won’t be return.
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)
