    jsapi-constructor-proxy: Inherit from js::Wrapper
    
    js::DirectProxyHandler and js::Wrapper are supposedly the same, except
    that js::Wrapper can expose the object it's wrapping to C++ code. We don't
    use that functionality. However, js::DirectProxyHandler is being removed
    in SpiderMonkey 52 in favour of js::Wrapper, so it makes sense to switch.
