DevTools: fix renderer crash when pause is pressed during page load
DevTools: fix renderer crash when pause is pressed during page load

Create an empty object template for the utility context global object instead of using ShadowObjectTemplate. The shadow object overrides some of the window properties(top, location,...) that led to a failure when accessing these properties since the template was not configured correctly(all its internal fields were undefined). In fact, we don't need the utility context global object to be a shadow object as long as inspected window global object is proto of the utility context global object.
