thought: We could use the same pairs of init and activate checks as in the test case 'deactivate instrumentation via config' here. On the other hand, the test setup only deactivates grpc, so to be honest, I do not remember why we check for all the other instrumentations here as well 🤔 I think just having expectations for grpc and maybe grpcjs for their respective init and activate methods would be enough?

though: We could merge this into 'deactivate instrumentation via config' instead of having a separate test case, see above.
