REGRESSION(275943@main): WebKit apps can crash on launch in
ApplicationStateTracker::setScene()

Reviewed by Eric Carlson and Andy Estes.
KVO will use a NSNull object as the value of a change when the windowScene
becomes nil. Detect this case
and call setScene() with nil rather than the NSNull object.
