efreet - fix efreetd kill and start with clean cache case blank icons

if you kill efreetd ANd delete all the caches, the restart of efreetd
will lose all icons until an app re-registeres icon extensions and it
can scan all icons .. and then app has to actually get the right
upodate events and do the update properly when this happens. this
fixes that scenario
