`parent` is compared to name so equivalent ID creates change

If you specify the correct ID of an existing group, the code compares to the group name, creating a change event.  For example, if the `All Nodes` group is the parent:

```
parent => '00000000-0000-4000-8000-000000000000'
```
Creates a change whereas:
```
parent => 'All Nodes'
```
is a noop.
