iOS 10: push notifications delegates not called

Number:rdar://27935982 Date Originated:20/08/2016
Status:Open Resolved:
Product:iOS SDK Product Version:iOS 10 beta 7
Classification: Reproducible:Always
On iOS 10 beta 7, when the user taps on a received remote notification while the app was in background, the ApplicationDelegate method 

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult result))handler

is NOT called.

We realised that if implemented, the legacy method 

-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo

is called in this case.

This breaks backward compatibility and would force us to update

Steps to Reproduce:
- Implement the method -[AppDelegate application:didReceiveRemoteNotification:fetchCompletionHandler:]
- Send app to background using the home button
- Send a remote user  notification to that app
- Tap on the received notification

Expected Results:
The delegate method -[AppDelegate application:didReceiveRemoteNotification:fetchCompletionHandler:] is called

Actual Results:
No notification delegate method is called.
