Async swaps on install

[NBKelly]

Added a unit test for yagi-uda, just relied on tests not breaking for daruma/midori.

Closes #7839

Is there ever a time we wouldn't want to async swap cards?

[NBKelly]

If neither or both of them are installed, there aren't any events that matter (at least for now).
Sooner or later I'll see about making all movement async.

[NoahTheDuke]

making all movement async would be... one hell of a pr. i've resisted it for years lol. the better move imo would be to change the engine to work on steps of some form and stop relying on callbacks (aka async). but that's also a lot of work... ;_;
