This previously caused a panic when moving lastKnownGood between two non-nil values, because we were comparing the interface wrapper instead of comparing the NodeConfigSources. The case of moving from one non-nil lastKnownGood config to another doesn't appear to be tested by the e2e node tests. I added a unit test and an e2e node test to help catch bugs with this case in the future.
