Select parameter for tasks endpoint has issues

[finicola]

Describe the bug
When querying https://graph.microsoft.com/v1.0/me/todo/lists/?$select=id,importance,title etc, the API returns every field. This also reproes if you select a task. Also, if you add "title" to the list of entities, the query breaks.

To Reproduce
Steps to reproduce the behavior:

1. Go to Graph explorer (consumer or enterprise)
2. Query https://graph.microsoft.com/v1.0/me/todo/lists/?$select=id,importance,title
3. See error

Expected behavior
Selected entities returned

"message": "Invalid request",
"innerError": {
"code": "RequestBroker--ParseUri",

}
}
}
