           Summary: DataRow.GetParentRows doesn't work with
                    DataRowVersion.Original

When calling DataRow.GetParentRows(relation, DataRowVersion.Original), the
index is queried which uses DataRowVersion.Default and not
DataRowVersion.Original.
Therefore an returned result is returned (usually null).


Reproducible: Always

Steps to Reproduce:
Test case:

            DataSet data = new DataSet();
            DataTable parent = new DataTable("parent");
            DataColumn pk = parent.Columns.Add("pk");
            DataTable child = new DataTable("child");
            DataColumn fk = child.Columns.Add("fk");
            data.Tables.Add(parent);
            data.Tables.Add(child);

            DataRelation relation = data.Relations.Add(pk, fk);
            data.EnforceConstraints = false;
            parent.Rows.Add("key");
            child.Rows.Add("key");
            data.AcceptChanges();
            parent.Rows[0][0] = "key2";

            Debug.Assert((string)parent.Rows[0]["pk", DataRowVersion.Original]
== "key");
            Assert.AreEqual(parent.Rows[0]["pk", DataRowVersion.Current],
"key2");
            Assert.AreEqual(child.Rows[0]["fk", DataRowVersion.Current],
"key");

            DataRow parentRow = child.Rows[0].GetParentRow(relation,
DataRowVersion.Original);
            Assert.IsNotNull(parentRow);

Actual Results:  
Null is returned from GetParentRow(relation, DataRowVersion.Original)

Expected Results:  
The parent row should be returned from GetParentRow(relation,
DataRowVersion.Original)
