Éric Lemoine 192c9d697e Unregister the viewport listener on setTarget(null) ...

This commit unregisters the viewport resize listener when setTarget(null) is called, and registers it when setTarget(target) is called, and when we don't have that listener registered yet.

This prevents memory leaks where references to map objects are retained because of these viewport resize listeners.
