    project-tree: use strcmp instead of g_utf8_collate to compare collation keys
    
    It seems it is possible for g_utf8_collate_key_for_filename() to return an
    invalid UTF-8 string, which causes crashes in g_utf8_collate() because the
    string cannot be normalized. According to the documentation of
    g_utf8_collate_key_for_filename(), we should just use strcmp() to compare
    its return value.
