Fix #142103: Animation decorator not working on Light Temperature value

When having a checkbox and a value both in one row together with an
animation decorator it is questionable whether the decorator should act
on animating the checkbox or the corresponding value.

We had similar cases before (e.g. 7c04ef210e)

In this case as well, one would think it is more desirable to animate
the actual Temperature **value** (instead of the checkbox), so this is
what this PR does.
