If you're testing the interface, changing the implementation internals won't create any churn (as the mocks and tests don't change).
If you are changing the interface, though, that would mean a contract change. And if you're changing the contract, surely you wouldn't be able to even use the old tests?
This isn't really a go problem at all. Any contract change means changing tests.
