**Describe the bug**
az boards query --id returns no items if the query is a tree of work items.

**To Reproduce**
Create a query on ADO; save it as tree of work items; run the command and it should return nothing.
Change the query to flat list of work items and rerun the same command; it will return the results.

**Expected behavior**
AZ cli should return a flat list of work items regardless if the query is a tree or flat list of work items.

**Environment summary**
az cli on windows 10
