When using the `render()` function in Twig with a `controller()` reference, the attributes can contain non-scalar. That's fine for the inline strategy, but it cannot work for other strategies as it then involves a proper HTTP request.

So, this PR properly throw an exception in such situations to avoid difficult to find bugs.
