Fixes #439

Is the correct fix for this not to update the @JsonProperty values in https://github.com/mc1arke/sonarqube-community-branch-plugin/blob/master/src/main/java/com/github/mc1arke/sonarqube/plugin/almclient/azuredevops/model/enums/CommentThreadStatus.java to match the values in https://docs.microsoft.com/en-us/javascript/api/azure-devops-extension-api/commentthreadstatus?

Either way works. I think this way makes it more fool proof, but it is up to you.

Part of the reason I'm suggesting changing the enum is that any serialised value produced by the service wont work after your change, since they wont match the possibly values supported by the API. We don't currently serialise these enum values so it's not currently causing an issue, but it's something we should fix in the right way if we can.

Merged, thanks for the quick turn-around on the fix.
