New feature: refunds go to original funding source.

I made the last scenario mis-understanding the way that the YAML scenarios worked.

Often, they have duplicate stuff with new names just to make sure that things work.
That means I don't need to translate them 1-1, I have to figure out which
thing is actually important and just do that.
