Logical Tree Tests not Being Run

### Describe the bug

Related to #472, it was reported that they couldn't see the tests when opening the Extensions component solution `\components\Extensions\OpenSolution.bat`.

Similarly, I don't see these tests in the test report in test space or the CI logs...

### Steps to reproduce

```text
Look for any logical tree tests from this file: https://github.com/CommunityToolkit/Windows/blob/main/components/Extensions/tests/Test_LogicalTreeExtensions.cs

Can't find test results...
```

### Expected behavior

Test results for these tests.

Commencez par components/Extensions/tests/Test_LogicalTreeExtensions.cs et components/Extensions/OpenSolution.bat, puis examinez comment ce projet de test est inclus dans la solution et dans l’exécution des tests CI. Reproduisez localement les résultats manquants et comparez le rapport de l’espace de test ou les journaux CI ; c’est terminé lorsque les tests de l’arbre logique s’exécutent et que leurs résultats sont visibles dans les deux rapports attendus.
