fix(chats): replying while editing a message drops the edit's text

reply() left edit mode but kept the edited message's prefilled text, so Send posted it
again as a new reply. It now cancels the edit, text included, in Marmot and in Concord
(which had the same bug). Checked on the tablet: Edit a message, Reply to another, the
composer is empty.
