Refresh list fully

[Samer]

If you have Local selected in view and All filter .. and delete a local package and use the rescan .. the package is still listed under local .. the list should be refreshed and be removed from the list ..
also if you have show only Downloaded selected and delete a package and press rescan .. the state does change but it's still showing under downloaded until you change view to All for example and then back to downloaded ...
what i think is best that the list should get blank and regenerate as if you're reopening the installer.
