Fix the revert button issue with instanced nodes

The method "check_reload_status" on the file "property_editor.cpp" didn't take into account if the field is a property of an instanced node just like the "update_tree" does. The code that checks this in "update_tree" has been extracted into the method "_is_instanced_node_with_original_property_different" to be also used in "check_reload_status".

Fixes #13415
