ResetUpdateStatus in external Web DataWindow

When a DataWindow has been retrieved from a database, calling ResetUpdateStatus after InsertRow resets the client context and no row is inserted on the client. This is expected behavior. However, when a DataWindow has been created using DataWindowSyntaxFromSql, the client context is not reset and a row is inserted on the client. If you make another change before calling ResetUpdateStatus, such as calling SetItem, the client context is reset and no row is inserted. [CR 380438]
