[@nativescript/local-notifications] getScheduledIds() returns ids of notifications that have already been published on Android

On Android if you schedule a notification and wait to receive the notification, the notification shows as expected. If you call getScheduledIds() after, that notification ID is still returned in the array and the array continues to grow infinitely unless you explicitly call cancel() or cancelAll().

iOS works as you would expect. Once you receive a notification, that ID no longer returns after calling getScheduledIds().

Comienza por la implementación de Android de getScheduledIds() y sigue cómo se eliminan las notificaciones entregadas del conjunto de programadas; compara ese flujo con el comportamiento de iOS descrito. Se considera terminado cuando el ID de una notificación entregada no aparece en los resultados posteriores de getScheduledIds() sin requerir cancel() ni cancelAll().
