      Description

      Since as far back as version 1.8, requests to create an {_id: -1} index have been treated as if they were requests to create an {_id: 1} index. These requests should return an error to the user instead of being silently treated as a different request.

      See also SERVER-14128 ("Creating _id index with unique:false should result in error").
