fix: onChange calls reduced to 1 when interacting with keyboard

[Gururajj77]

Closes #18386

Fixed the onChange from getting fired twice.

Changelog

New

• added the condition highlightedIndex === -1 to make sure the onChange fires only if the inputValue does not match with any of the items.

Changed

• modified a test's state updation for better checking.

Testing / Reviewing

• check the test story and interact with the keyboard
• check the console and see it does not have 2 console logs when we select items once.
