btc: wallet history classifies Swap transaction type incorrectly

[norwnd]

I've noticed Bitcoin SPV wallet history has a bug:

namely it seems to be classifying Swap as Refund, while not showing the actual Refund transaction that is currently in mempool - you can see on screenshot above:

1. I received funds and then
2. there is a Refund without any prior Swap (there is Acceleration transaction I've issued after swap has been stuck for some time, and that's what got Swap transaction mined couple of hours later - but at that point Match was revoked and it switched to refunding flow as it should)

Match-card page shows all 3 transactions (Swap tx, separate Acceleration tx, pending Refund tx) correctly.

After browsing through the relevant code I'm thinking this adjustment should resolve the issue (it relaxes the requirement on Swap/Send transactions to have tx.Send == true and looks like this is how it's done for zcash as well)
