Perhaps a simpler solution is to:
- remove the exception that shows the default deck when there are no other decks
- hide it from the browser sidebar unless it's non-empty
- add a new, normal deck like 'my first deck' when new collections are created, or show 'no decks' until the user adds/imports a deck
