Reproduction

- Create a MatTreeComponent with a NestedTreeControl and MatTreeNestedDatasource
- Test the component structure
https://stackblitz.com/edit/harness-issue-xgqlpl?file=src/app/tree-harness-example.spec.ts
Expected Behavior
The structure should have as many children (2 in the Stackblitz example) as visible Nodes.
{ children: [ { text: "Group 1"}, { text: "Group 2"} ] }
Actual Behavior
The structure has only one children without text.
{ children: [ { text: ""} ] }
