Fix for folding "Editable Children" nodes in Scene tree not being saved

[yahkr]

closes #91542

When _fill_folds is called on a child of an instantiated scene with editable children enabled, it will not be parsed correctly on child nodes due to the is_editable_instance check never being true.

Changed:

if (p_node->get_owner() != p_root && !p_root->is_editable_instance(p_node)) {

if (p_node->get_owner() != p_root && !p_root->is_editable_instance(p_node->get_owner())) {
