Short Description and Why It's Useful

• Added support for scanning product from the sarchbar and incrementing count accordingly.
• Fixed Incorrect Product Count Display in Counted Tab on Store View Screen.
• Fixed issue related to Variance is not being reset when new items are being selected

New Behaviour:

• When user search an product for the first time, it comes in the view.
• In case of pending items, it will increment count on each scanning if product is already in the view.
• In case of counted items, on scanning item comes in the view, but count increment will start after manually enabling Re-count.
• On scanning product, the updated count will be saved on scanning a new item. Also the last item count need to be saved manually.
• On changing tab, or clicking back button we show and alert that all updated count will not be saved for confirmation.
