      The ShardLocal aggregations code ends up calling RSLocalClient. This code ends up overriding the readConcern given to the command.

      The readConcern given as a result would crash the server if snapshot readConcern is used since the override would swap afterClusterTime with afterOpTime. When processing the request, the server would also add a atClusterTime since it uses snapshot readConcern. This will cause this invariant to get hit since both arguments will be set.
