This PR was caused by the fact that we now no longer ignore the error from unregister topic validator.
@Wondertan brought up a good point that the API of
Subscriber
doesn't enforceSetVerifier
so it's possible to successfully Start the Subscriber without mounting a validator on it, but Stop would fail due to no validator being present.This PR reverts the change and logs/ignores the error from unregister topic validator.
