Summary:
Sending a push notification with the "content-available" tag is supposed to wake up the app in the background and call "application:didReceiveRemoteNotification:fetchCompletionHandler". It works well on iOS 7.0.6, but not on iOS 7.1.1.

Steps to Reproduce:
1. Create an empty iOS application project. Launching it should display a plain white view.
2. Ask for push permissions when the app starts, and print the push token in the console.
3. In the target settings (Capabilities -> Background Modes) enable "Remote notifications".
4. In AppDelegate, implement "application:didReceiveRemoteNotification:fetchCompletionHandler". Make it change the window's background color to red and NSLog("Application did receive remote notification").
5. Run the app from Xcode (Product -> Run).
6. Close the app from Xcode (Product -> Stop).
7. Double press the Home button: the multitasking screenshot of the app shows a plain white view.
8. With a program such as nomad-cli (http://nomad-cli.com/), send a push notification to your device with the "content-available" tag (option -n with nomad-cli): the push notification should appear on the Home screen.
9. Double press the Home button and check the color of the multitasking screenshot.

Expected Results:
If the app was launched in the background and "application:didReceiveRemoteNotification:fetchCompletionHandler" was called, the multitasking screenshot should be red. Moreover, the console logs in the Xcode Organizer should display "Application did receive remote notification".

Actual Results:
On iOS 7.0.6, the multitasking screenshot is indeed red. Moreover, the console logs in the Xcode Organizer display the following logs:

On iOS 7.1.1, the multitasking screenshot stays white, and the console logs in the Xcode Organizer don't display anything.
