This needs to be initiated in one place and then propagated through parameters. Looking at the calling tree of the various getIssue methods, this looks like a pretty bad mess. Not sure how to untangle this to propagate the version value.

I think the calling tree of `issues()` is in a mess because we have two different type of issues(`org.openjdk.skara.vcs.openjdk` and `org.openjdk.skara.issuetracker.Issue`). Besides,  we don't have class fields to store issues, csrIssues, JepIssues. So we need to call `issues()` three times.
