Hmm, I think this arises from a mindset that doesn't treat tests as part of the code that should be maintained and refactored.

You always have to be removing and refactoring tests if you are changing your production code. Changed a sorting algorithm? Good, go and have a look at your tests to see whether there's anything that doesn't need to be tested anymore, or edge cases that need to be tested now that the algorithm has changed.
