Subject: [PATCH] notifications: Don't crash because of zero-length string

Check whether given application child is at least 1 character
long to avoid crash which can happen as a result of creating
of GDesktopAppInfo with NULL desktop file id.
To reproduce this run "gnome-control-center notifications" and
"gsettings set org.gnome.desktop.notifications application-children "['']"".
