PR Summary

• Addition of a New Test Method
  A new method named testOldAttributeAfterInsertAndUpdate has been added to the ActiveQueryTest.php file. This method evaluates the performance of getOldAttribute function under the Customer class. Essentially, it creates a new Customer instance, sets its attributes, saves it, and monitors any changes to the 'name' attribute, specifically checking its previous values before and after any updates.
