[Qt] loads APP directory when calling "window.open"

[Yi Shen]

When creating a new window by calling "window.open('http://www.cnn.com')", it loads the "file://$${applicationpath}" because the ChromeClientQt::createWindow() never check the request whether is empty or not, and it loads the app directory when the request is empty.

When calling window.open('http://www.cnn.com'), the WebCore::createWindow() first 1) call client to create a new window 2) load cnn.com by calling changeLocation(); While in step 1), qt's chrome client always tries to load an empty request.

I think we should check the request because 1)it helps the performance 
                                            2)I found the gtk's createWindow checks the request every time. e.g. In ChromeClientGtk.cpp:129

Page* ChromeClient::createWindow(...) {
  ...
  if (!frameLoadRequest.isEmpty())
      webkit_web_view_open(....);
}
