[Notifications] Chop "." off destination URL
It means "current directory" anyway, so it's redundant and ugly.
desktop:/ KIO seems to rewrite its root URL to $HOME/Desktop/.
which results in a "Copying to Home/Desktop/." to show up. With this patch it's now "Home/Desktop".
The Desktop entry in Places panel doesn't actually point to desktop:/
but the actual file system location, that's why it doesn't just show "Desktop" (could be done as a special case separately).
