 * @description
 * This checker does nothing except for hydrating the Order in order to test
 * an edge-case which would cause inconsistencies when modifying the Order in which
 * the OrderService would e.g. remove an OrderLine, but then this step would re-add it
 * because the removal had not yet been persisted by the time the `applyPriceAdjustments()`
 * step was run (during which this checker will run).
