[EGIT PATCH 2/5] Don't crash the decorator update loop when resources are deleted

["Shawn O. Pearce" <spearce@spearce.org>]

If a resource is deleted from the workspace we don't need to clear
its GITFOLDERDIRTYSTATEPROPERTY from the item because it is gone.
There won't be anyone else to query for that flag, so the flag is
not relevant anymore.  Further trying to call accept() on those
resources throws an exception because Eclipse won't let you touch
a deleted resource.
