When mount the component, will error!

I found when I mount a component, it will render a commend node.But if I change the source of mount function like this:

export function mount (component, options) {
  if ( options === void 0 ) options = {};

  if (!window) {
    throwError('window is undefined, vue-test-utils needs to be run in a browser environment.\n You can run the tests in node using JSDOM');
  }

  var componentToMount = options.clone === false ? component : lodash.cloneDeep(component);
  // Remove cached constructor
  // delete componentToMount._Ctor;
  var vm = createConstructor(componentToMount, options);

  if (options.attachToDocument) {
    vm.$mount(createElement());
  } else {
    vm.$mount();
  }

  return new VueWrapper(vm, { attachedToDocument: !!options.attachToDocument })
}

I remove the statement delete componentToMount._Ctor, it will work!

@74sharlock sure, as you wish #1207

However issue like that looks a little excess for me, probably more general issue about documentation is needed.
