fixup! [keyboard applet] fix TypeError garbage in log

New error:
/usr/share/plasma/plasmoids/org.kde.plasma.keyboardlayout/contents/ui/
main.qml:17:5: Unable to assign [undefined] to QString

This is because just string is returned and not an object.
The expression should always return struct with proper fields instead.
