Tests not passing

When running the tests locally with `go test`, they are failing.

Here's a link to the complete output: https://i.fluffy.cc/43V1dWkmPvGN3SBBbwtbGTX10bkqs7jw.html

A lot of these errors seem to be from golint, which is throwing the message:

```
"golint": "comments: package comment is detached; there should be no blank lines between it and the package statement
```

Our tests seem to not expect this message. Maybe this was a change in golint?

We probably should also consider alternatives to golint, as it has been deprecated (related issue: https://github.com/exercism/go-analyzer/issues/16)
