QmlDesigner: Fix clearing node lock/eyeball

Lock/eyeball status was not propagated to puppet when lock/eyeball
was cleared, as clearing these aux properties instead removes them,
which triggers change notification with invalid value. Fixed by
allowing invalid value to be propagated for these properties.

Fixes: QDS-8735
