Fix the "wait for execution" behavior when clicking on Search tab

Follow this scenario to reproduce:

1. for the default content view displayed when you click on the Search button in the Main tabs, set the waitForExecution attribute to true on the corresponding content view (check the "Wait for execution" box in Studio)
2. update your application with this change
3. log in
4. click on the Search button in the Main tabs
5. the main content displays some results

The expected behavior is to see the waitForExecutionSentence in the main content and no document.
