[GAMEPLAY] Kindred loses all stacks if the summoner exits/reenters the game or if the game crashes.

Exactly as the title says, when the player exits or the game crashes and they enter back, kindred's stacks are reset to zero.

1. Play game as Kindred.
2. Get some mad stax.
3. Force close the client.
4. Reenter game.
5. No more stax and all further stax are happy, not mad.
