Summary:
Nodes crashed when setJSResponder was called on a virtual (non-View)
node, because a View could not be found using that react tag. The solution is
two fold - first, to figure out the View parent and pass that to
setJSResponder in addition to that of the virtual tag. Secondly, we weren't
mounting views that had animation properties (transform, for example) to
Views, which caused related code to fail.
