Puzzle streak reset when app is terminated

[ijm8710]

Per Tom's comment in #1262, it appears the intention is for it to be saved. But if I play a few puzzles and force quit the app and then restart it and try resuming puzzle rush, I see myself back at 0.

The more practical application of this is if you're playing and phone dies in the middle.

Perhaps it only saved when you Backswipe out. Not sure, but as far as I can tell when ive tested, it's not saving after each increment puzzle success which I would think is the intention.
