A short Unread list read through no longer says more to load (#385)

hasMore() compared nextOffset(), which on Unread counts only the loaded
items still unread, with S.total from the answer: once they were read it
was 0 against that total, so the page asked for a page that came back
empty and took its total, 0, with the items still on screen. Whether
more is left now comes from the last answer itself, its offset and items
against its total; reading takes an item off the server's list and off
nextOffset() alike, so what that answer said is left stays true.
