issue #23796 - csv export from gridbox

That's four parents, which is going to be fragile to any change in our enyo components array. Getting the `attr` field (using two parents) is probably the best way to do it, but for the `recordType` and the `uuid`, I'd say, don't figure these out here and pass them up through the event. Rather, when you receive the event in the `workspaceContainer`, you can get these values as `this.$.workspace.value.recordType` and `this.$.workspace.value.id`.

Note also that I was expecting you to use the `idAttribute`, which might not be the `uuid`. I guess `uuid` will pretty much always work, but typically we query things more like this: `{attr: model.idAttribute, value: model.id}`
