more responsive UI when Favorites are used.

- The reloading of items in the favorite widgets is now done async, so it does not block the UI when opening Home.
- Tasks that check for changes of the widget and favorites are now terminated when another view e.g. Subscriptions is opened.
- We only update the Favourites when the player is not in the foreground, to avoid unresponsiveness.
