Existing updates not shown when download path changes

[Zxian]

To reproduce:

1. Download a number of updates to a folder. Let's call it C:\Updates
   
2. Downloaded updates should now be highlighted green in WUD
   
3. Close WUD
   
4. Rename the C:\Updates folder to "C:\WUD stuff"
   
5. Open WUD. Previously downloaded updates should be white (unhighlighted)
   
6. Change the download path to "C:\WUD stuff"
   
7. Updates that were downloaded are still not highlighted
   
8. Close and open WUD - updates are now highlighted
   

It's basically just that the highlighting isn't being updated after you change the download path.
