Why remove these?

To allow the slotItemsChanged to be called when new data about fileSize arrives.
It is needed to have progressive ordering of folder while the worker is walking through the directories.
Otherwise the view does refresh the column size as the results arrives.
The view is still updated with a delay to batch UI changes (m_recentlyChangedItemsTimer).

I see. Please do mention this "progressive ordering" in the commit message.
