Oops, we should also have getIsolateFromFrame, at least I claim in
https://chromiumcodereview.appspot.com/23788005/ that I added it, but something
went wrong :/ Anyhow, I'm fixing it here:
https://codereview.chromium.org/24119002/ and this CL should use that func.

isolateForFrame() does:
frame->script()->isolate()

while this file does:
frame()->script()->currentWorldContext()->GetIsolate()

Is this really the same? Can I safely replace?

         results->swap(v8Results);
     } else
         frame()->script()->executeScriptInIsolatedWorld(worldID, sources, extensionGroup, 0);
