Cobblestone walls in taiga villages have incorrect blockstates

The bug

The library in taiga villages has walls in front of it that look like they're connecting to an invisible block. This happens because there's a jigsaw block in the structure file there, and the walls aren't updated upon being generated into the world.

This also affects taiga_cartographer_house_1.
