[ReactNative] Ensure WebViewExecutor's webview is created on the main thread 

Summary:
Fixes #2464

After the bridge parallelisation of the bridge initialisation the executors
were being `setUp` in a background thread, and the `RCTWebViewExecutor` was
crashing when creating a `UIWebView` out of the main thread.

Wrap the `UIWebView` creation in a call to the main thread.
