Fix the logic for updating the shortuct labels when the display names

of the corresponding folders change, so that it doesn't crash.

I have removed the redundant "folder_updated" signal on
`ELocalStorage' and changed EStorage so that it emits "updated_folder"
automatically when any of the folders changes its properties.
