Avoid LINQ exception (#5933)

* Avoid LINQ exception

If the back button in UWP is pressed, but there's nothing in the backstack, the `Last()` LINQ query will throw `System.InvalidOperationException: 'Sequence contains no elements`
This change avoids that, and just returns false that Forms didn't handle the event.

* Change to use LastOrDefault
