client.Changes.SetReview fails with 401 Unauthorized

For the installation of Gerrit I'm using, the following code fails:

package main

import (
    "fmt"
    "github.com/andygrunwald/go-gerrit"
)

func main()  {
    client, err := gerrit.NewClient("<server>", nil)
    if err != nil {
        panic(err)
    }

    username := "<username>"
    password := "<password>"
    client.Authentication.SetDigestAuth(username, password)

    input := &gerrit.ReviewInput{
        Message: "FOOBAR",
        Drafts: "PUBLISH_ALL_REVISIONS",
    }
    info, response, err := client.Changes.SetReview(
        "<change-id>",
        "<revision>",
        input,
    )
    if err != nil {
        fmt.Println(response)
        fmt.Println(err)
    }
}

With this output:

API call to <server>/a/<change-id>/revisions/<revision>/review failed: 401 Unauthorized

Interestingly, it works using cURL:

curl -XPOST -v <server>/a/changes/<change-id>/revisions/<revision>/review' -H 'Content-Type: application/json' --data '{"drafts":"PUBLISH_ALL_REVISIONS","message":"FOOBAR"}' --digest -u <username>:<password>

And produces (content modified to show general request flow)

> POST /a/changes/<change-id>/revisions/<revision>/review HTTP/1.1
> User-Agent: curl/7.43.0

)]}'
{}

For some reason, /review seems to handle the contents of the request a little differently. I'm still trying to figure out why exactly. At first /review was returning a broken response but that turned out to be because we're reusing the request body for digest auth. With that being fixed by #12, I'm opening this issue to track the fix for /review.
