Fix go vet issues (#720)

* Fix go vet issues

* to omit the property from JSON parsing one should use "-". "omit" in
that case would use omit tag
* The error was not reachable in the tests, so I moved it to the place
where it make sense for me (but maybe it was just unnecessary)

* Run all go vet linters in CI

* This return breaks the test
