Get<T>(list) throws ArgumentException when keys are empty

IDictionary<string, IOperationResult<T>> CouchbaseBucket:Get<T>(IList<string> keys) will throw an ArgumentOutOfRange exception raised by the Partitioner.Create call when the keys list is empty. Currently we can avoid this scenario but ideally we imagine that it should result in an empty dictionary as the previous 1.3 version. It would be nice to know if this will be the case in future versions.
