Summary:
From the UIDocumentPickerExtensionViewController, -[NSExtensionContext completeRequestReturningItems:completionHandler:] dismisses the document provider UI but does not return any items to the host app.

While UIDocumentPickerExtensionViewController has a dismissGrantingAccessToURL: method, this NSExtensionContext method is important because this method provides a completion handler block argument which is necessary for cleanup.

Steps to Reproduce:
Step 1: call the following code from a UIDocumentPickerExtensionViewController.

NSURL *path = ...;
NSExtensionItem *item = [NSExtensionItem new];
item.attributedTitle = [[NSAttributedString alloc] initWithString:path.lastPathComponent];
item.attachments = @[[[NSItemProvider alloc] initWithContentsOfURL:path]];
[self.extensionContext completeRequestReturningItems:@[item] completionHandler:^(BOOL expired) {
    NSLog(@"In beta 5, this does get executed");
}];


Expected Results:
1. The document provider extension is dismissed
2. The URL is passed to the host app, which can then open the file
3. The completion handler is called

Actual Results:
The document provider extension is dismissed and the completion handler is called, but the host app's documentPickerWasCancelled: is invoked rather than documentPicker:didPickDocumentAtURL:.
