    starred-directory: Actually implement ::force_reload
    
    The code created to handle the NautilusTagManager::files-changed signal
    has been reused for implemeting the NautilusDirectory::force_reload
    virtual function.
    
    This is conceptually wrong, because the update_files function doesn't
    actually reload the file list. Also, as a side effect, it causes gone
    files to reappear as "ghost files" (files without any attributes).
    
    Instead, let's follow what NautilusSearchDirectory does: clear the
    current file list after unmonitoring the files, and set the file list
    anew the same way it's done on ::init.
