    [POP3] Message re-download shown as completely empty message
    
    For messages which are stored in the cache, but their UID is not
    known for any reason, are not downloaded from the server again, but
    are passed from the cache instead. The problem was that the cache
    stream was not populated, which produced completely empty message.
