Message Logger: hidden messages on the server, removed chats, old chat photos

- Hidden deleted messages are marked on the server (local marks migrated);
  "Reveal hidden messages" in the chat menu, Unhide in the message menu and
  the selection bar.
- Chats an account lost are reported, listed among its chats again and
  opened read-only with their logged messages, all deleted.
- Logged chat photos: a removed chat's avatar, and in a chat's photos the
  ones it no longer has, translucent with a trash icon in the viewer's
  previews.
- Fix: the deleted-post comments thread is answered locally again.
