StaticReactRenderer is not constructed correctly if limenius_react.react_renderer service is not defined

[rakelley]

#33 broke compatibility with default_rendering: "client_side" configuration, as \Limenius\ReactRenderer\Twig\ReactRenderExtension::__construct() blindly calls \Limenius\ReactRenderer\Renderer\StaticReactRenderer::setRenderer() without checking if the renderer is null.

Everything works with server_side or both, or if you have a custom service defined for limenius_react.react_renderer, but by default there is no guarantee of such a service existing.

This should actually be on ReactRenderer, sorry

A quick solution to make client_side work on Symfony4 is.

In services.yaml add under services :

    limenius_react.react_renderer:
        class: Limenius\ReactRenderer\Renderer\StaticReactRenderer
