Swap operation results in "Backup Tx receiving address not found in this wallet!" error

I ran `cargo run --bin cli -- wallet swap -i <state-chain-id> -s <swap-size>`, being 2 as `swap-size`, using 2 wallets and both daemons returned:

> thread 'tokio-runtime-worker-2' panicked at 'called `Result::unwrap()` on an `Err` value: Generic("Backup Tx receiving address not found in this wallet!")', client/src/daemon.rs:302:26
