Fix next-step hints: cryptic destiny hint, hide completed adventures count

- Don't show "Adventures: 9/10" when all unlocked adventures are done
  (the 10th is Destiny which isn't unlocked yet, confusing the player)
- Only show adventure count when there are incomplete unlocked adventures
- Replace misleading "complete all adventures" destiny hint with a
  cryptic "keep opening boxes" hint (Destiny unlocks via box_endgame drop)
