wireprotov2server: use our CBOR encoder Again, test output changed slightly because of map key ordering differences. This shouldn't matter. I could have called oncommandresponsereadygen() with the raw output from the stream encoder. However, this changed test output further. I left a TODO to follow up on that later.
