test: control serialization: Test lookup by ControlId

Test that lookup by ControlId reference works in the control
serialization test making sure that the control limits are not changed by
de-serialization.

The test currently fails and demonstates that lookup by ControlId is
currently not supported until the introduction of the next patch.
