This PR ensures the custom post type wptests_pt registered during tests in Tests_User_GetTheAuthorPosts is cleanly unregistered in tear_down() using the public unregister_post_type() function, preventing fixture leakage and replacing the internal mid-test call.

Thanks @devmuhib009!

Properly unregisters the wptests_pt custom post type in tear_down() and removes the mid-test unregistration call in Tests_User_GetTheAuthorPosts, preventing fixture leakage across test suites. Looks good to me!
