Example Project that demonstrates the problem

The example project that demonstrates the problem in the WKWebView that this change is trying to solve.

1. Compile and run the project in an iPhone Simulator.
2. When the simulator launches, click on the button in the main view called "launch modal web view".
3. Click the "Choose File" button.
4. Select "iCloud" or "Photo Library" from the menu.
5. The modal web view gets dismissed by this WebKit bug.

The web view should not get dismissed.  The problem here is that the WebKit is trying to close a UIDocumentMenuViewController by calling dismissViewControllerAnimated.  The UIDocumentMenuViewController automatically dismisses itself.  This extra call to dismissViewControllerAnimated is dismissing the modally presented WkWebView.
