Fix - Spotlight - index out of bound

[xypnox]

Description

• Add behavior to reset index when out of bound
  Index is reset to the last item when the index of the active elements exceeds the number of items when a change occurs in the number of items, via search query changes etc.

Motivation and Context

Earlier the index remained as what it was even if the number of items changed to a lesser quantity and the user had to manually use the up arrow key to make it focus on any of the lesser items.

How has this been tested?

Using keyboard to change index and the search query in spotlight.

Screenshots (if appropriate):

NA
