In KItemListController::slotChangeCurrentItem searchFromNextItem use was bugged :
The two branches of `if (searchFromNextItem)` both looked for the next keyboard with indexForKeyboardSearch(text, currentIndex (the first one with just a +1 modulo).
But when searchFromNextItem is false, we are supposed to start to look for the next indexKeyboard from the start of the list `0`, not from the `currentIndex`
