LookupIn replicas not available tests failing on servers without support

LookupInAnyReplica:
Per the RFC we expect a SDK feature not available exception, however we are seeing the Dotnet SDK/performer returning a normal result and not indicating to the user/driver that the feature wasn't used.

LookupInAllReplicas:

Per the RFC we expect either the initial operation or the overall stream to fail with an SDK feature not available exception. Instead we see the SDK/performer returning a stream with 2 items. The first is a successful operation presumably fetched without using replicas and then the second item is an SDK invalid argument exception rather than the expected exception.
