Title:

Refactor to use JpaRepository default implement

---

Description:

This PR refactor the OwnerRepository, implementing with JpaRepository instead of Repository interface. Remove the rest @Query in OwnerRepository class. Also refactor code logic in test and controller files.

---

Solution:

• Replace: use JpaRepository to replace Repository in OwnerRepository class.
• Rename: rename method findByLastName into findByLastNameStartingWith which can be auto-generate.
• Remove: remove useless annotations.
• Refactor: refactor test and controller code logic.

---

Additional Information:

This is just a part task to refactor the OwnerRepository with JpaRepository. Also need to do the same thing with VetRepository, but next step is to write more unit tests in PetControllerTests.
