    Update BuildRequest if instance currently being scheduled
    
    There are some cases where the instance is still waiting to be scheduled and
    consequently there is still a BuildRequest object where we would also like to
    update the instance attributes, like the display name.
    
    In that case, we need to update the nested instance field from the BuildRequest
    instead of trying to update the instance object itself, which could be located
    in a child cell.
