Change address automatic labelling of destination addr label + prior receive addr

**Current behavior:** change UTXOs are labeled by their index.

**Ideal behavior:** Automatically label change UTXOs with (a) the recipient(s) label when it gets spent (ie., address labels of destination addrs) and (b) receive address labels.

E.g., if user generates new address bc1...x and labels it "John" and receives funds to it, then spends this UTXO to a destination labelled "Jane", then if there was change, said change would be "Jane, Jane"

The user can of course, today, normally edit the label to achieve the same outcome, but it happening automatically would be neat. The above is same behavior Wasabi has.
