Damus stores npub as both Strings and URLs in NSAttributedString.Key.link when a note is saved as a draft. Make Damus correctly handle both when we retrieve and store drafts. Changelog-Changed: Handle npub correctly in draft notes Signed-off-by: Askeew <askeew@hotmail.com> Closes: https://github.com/damus-io/damus/issues/2923
