Motion v0.5.0 does not work with ViewComponent >= v2.35.0

[bert-mccutchen]

Motion fails to serialize the component due to ViewComponent v2.35.0 changing some instance variable names:
ViewComponent/view_component#967

This means @controller and @helpers are now @__vc_controller and @__vc_helpers, which are not excluded here:
https://github.com/unabridged/motion/blob/v0.5.0/lib/motion/component/rendering.rb#L8-L29

As far as I can tell, this only happens when you have a form in the view component's HTML.

Looking into this further... There are actually many more that are of issue, for example @variant is now @__vc_variant. The entire list will need to be reviewed and updated with a patch.
