Update Javascript memory management a bit.

Browse source 
* bindings/vapi/javascriptcore-4.0.vapi: Don't pretend JS.String will
  be unreff'ed by vala, it wont. Add JS.GlobalContext.retain, in case it
  wants to be used.

* src/client/components/client-web-view.vala
  (ClientWebView::ClientWebView): JavascriptResult instances are unref'ed
  when unowned.
