Unnecessary queries to get all children entries

Description

If a node is updated, CatalogNodeAdmin loads all of its children entries (recursively) to send to IChangeNotificationManager for indexing. However, this is only necessary if the code or the node's UriSegment was changed. Other changes should not trigger that.

This can cause performance issues if customer has a big/complex catalog with multiple nodes. If customers import multiple small chunks continuously, this behavior is a bottleneck.
