fix: keep stream titles when playlist:edit saves the file

playlist:edit saved the playlist without the raw option, so every title
was rebuilt from the API channel name and country instead of being
written back as read. For a stream whose channel is not in the database,
that becomes "undefined (undefined)". playlist:format, playlist:update
and playlist:test already save with { public: false, raw: true }.
