    Leftover "Generating message list..." info in a message-list
    
    In some cases, like on errors or cancel, there could be left
    an information in the message-list that the list is generating
    its content, while it didn't do it in reality. This always resets
    the message-list information in case the current message-list
    generation finished and was the last in the queue.
