[nautilus/wip/antoniof/gtk4-preparation-batch-rename-dialog: 4/5] batch-rename-dialog: Don't keep a list of rows

[António Fernandes <antoniof src gnome org>]

commit ca9a2cc978e6b4d3f1227edaffec8cf1dce5b6a8
Author: António Fernandes <antoniof gnome org>
Date:   Sat Aug 14 12:55:32 2021 +0100

    batch-rename-dialog: Don't keep a list of rows
    
    We already have a list of their children, so we can just call
    GtkWidget::get_parent().
    
    This prepares for the next commit to drop direct rows creation.
