D7535: Don't special case file URLs when processing .desktop files

Restricted Application added a project: Plasma.
Restricted Application added a subscriber: plasma-devel.

REVISION SUMMARY
  At first glance this looks faster, as we skip KIO for a simple stat(),
  but as the result isn't cached we do file lookups on every single mouse
  move.
  
  This also has the side effect of not blocking Plasma when stat-ing a
  file on a disconnected remote drive.
  
  CCBUG: 379994

TEST PLAN
  Created two .desktop files one pointing to a dir, another to a file.
  One had the arrow to expand the folder, the other did not.

REPOSITORY
  R119 Plasma Desktop

BRANCH
  master
