Discussion at the client sprint: we should encapsulate the SourcePackageRelease handling within PackageCopyJob rather than passing it in from sites that create the jobs; but since PCJs never end up in DistroSeries:+queue until they've been partially run and decided to suspend themselves, they could compute their own SPR links at that point. That would still require a new DB column.
