    [IMAPx] Miscellaneous changes
    
    - cache_stream in get_message can be NULL, thus count with it and
      do not cause runtime warning from g_object_unref()
    - if the whole folder content is removed on the server the local
      folder cache wasn't cleaned up, still showed cached message list
