Depsgraph: Fix/workaround for a drivers using lamp settings as variables

Not sure what's the designed way dealing with this, so if Joshua can clarify this a
bit that'd be really nice :)

For now it's so called "seems to work in the test file", added a TODO in the code so
we don't forget to doublecheck on this before merge.
