Use Case

The server selection specification states that drivers MUST NOT attach a $readPreference field to commands destined for a stand alone. Node does, in a follow up PR to runCommand spec work: https://github.com/mongodb/specifications/pull/1416 a test is added that the node driver will, currently, fail.
