SAVEGAME CORRUPTED

For human player too.

Fixed d23f6c7.

The same bug breaks Ire of Kaminari, Hana Kami, Unbreathing Horde, Angel of Flight Alabaster, Ghoulcaller's Chant, Horde of Notions, Hakim, Loreweaver, Auriok Survivors, Soulless One, Lord of the Undead, Loyal Retainers, and Thelon of Havenwood; it makes all queries for the number of cards in a player's graveyard of a given subtype be 1. If there's bugs open for any of those with matching symptoms, they're all fixed too.

(It's all the worse since it's a result of a clumsy cut-paste-modify of a different function, any_in_graveyard_by_subtype(), which A) works properly, B) stops looking after the first matching card found, and C) is sufficient for almost all of the cards above.)
