This is just a minor conceptual clean-up, runtime behaviour is not being changed, as ultimately, much later in the exec flow, the msg object being passed around is cast to str already. (e.g. see str(text) at https://github.com/spesmilo/electrum/blob/4f7b6e897710338e8a4cfb8fa97c305218bdff88/electrum/gui/qt/util.py#L375-L379)
