Bug

**What is the current behavior?**

React Native for Web was broken by 16.5 as describe [here](https://github.com/necolas/react-native-web/issues/1096) due to this change https://github.com/facebook/react/pull/13539

**What is the expected behavior?**

Release a version of React that exports the EventPluginHub.

**Which versions of React, and which browser / OS are affected by this issue? Did this work in previous versions of React?**

Worked in 16.4
ReactTestUtils.Simulate = {};
  let eventType;
  for (eventType in eventNameDispatchConfigs) {
    /**
     * @param {!Element|ReactDOMComponent} domComponentOrNode
     * @param {?object} eventData Fake event data to use in SyntheticEvent.
     */
    ReactTestUtils.Simulate[eventType] = makeSimulator(eventType);
  }
}
buildSimulators();
/**
 * Exports:
 *
 * - `ReactTestUtils.SimulateNative.click(Element/ReactDOMComponent)`
 * - `ReactTestUtils.SimulateNative.mouseMove(Element/ReactDOMComponent)`
 * - `ReactTestUtils.SimulateNative.mouseIn/ReactDOMComponent)`
 * - `ReactTestUtils.SimulateNative.mouseOut(Element/ReactDOMComponent)`
 * - ... (All keys from `BrowserEventConstants.topLevelTypes`)
 *
 * Note: Top level event types are a subset of the entire set of handler types
 * (which include a broader set of "synthetic" events). For example, onDragDone
 * is a synthetic event. Except when testing an event plugin or React's event
 * handling code specifically, you probably want to use ReactTestUtils.Simulate
 * to dispatch synthetic events.
