## Description
Fixes marshaling error in sdk
closes https://github.com/cosmos/cosmos-sdk/issues/8578
the output stays the same, we are avoiding the passing of the callback because sdk uses typed logging.
## Description
partially cleanup in preparation for errcheck
i ignored a bunch of defer errors in tests but with the update to go 1.14 we can use `t.Cleanup(func() { if err := <>; err != nil {..}}` to cover those errors, I will do this in pr number two of enabling errcheck.
ref #5059
The service logging can be a bit unclear. For example, with state sync it would log:
```
I[2020-04-20|08:40:47.366] Starting StateSync module=statesync impl=Reactor
I[2020-04-20|08:40:47.834] Starting state sync module=statesync
```
Where the first message is the reactor service startup, and the second message is the start of the actual state sync process. This clarifies the first message by changing it to `Starting StateSync service`.
