Ensuring that we skip item decoration drawing when there are no apps.

        @Override

        public void onDraw(Canvas c, RecyclerView parent, RecyclerView.State state) {

            List<AlphabeticalAppsList.AdapterItem> items = mApps.getAdapterItems();

            if (items.isEmpty()) {

                return;

            }

            for (int i = 0; i < parent.getChildCount(); i++) {

                View child = parent.getChildAt(i);

                ViewHolder holder = (ViewHolder) parent.getChildViewHolder(child);
