DeviceGestureServiceOnGoBackRequested fires two times on Win10 UWP

[SunboX]

The DeviceGestureServiceOnGoBackRequested fires two times on Windows 10 Mobile. That leads to the app exiting instead of just navigation back to the main view. This is because of the Prism library listening for two events:

• HardwareButtons.BackPressed
• SystemNavigationManager.GetForCurrentView().BackRequested

Regarding to the Microsoft docs:

In Windows 10, the back button event is a universal concept. Back buttons implemented in hardware or in software will all raise the BackRequested event, so that's the one to handle.

..the hardware back button should only be handled on Windows Phone (...<=8.1 ... not Windows 10 Mobile)
