New Connection/ Lost Connection
I've been receiving tons of these messages in my ASB output: 
```
DEBUG New connection established peer=[]
DEBUG Lost connection to peer: Connection error: I/O error: connection is closed peer=[]
```
I just decided to make a swap with myself, but **canceled before btc deposit**, and now every time I run `swap list-sellers`, these messages pop in my ASB output. Apparently ASB thinks I'm back to continue the swap. I think we need a proper way to quit a swap.

- Software version: `asb` and `swap` v083, v090
