Copying packages between series can close the wrong bugtask

[Julian Edwards]

An evolution package was uploaded to intrepid-proposed which fixes bug 285520. It correctly did not close the bug because it's targeted to the -proposed pocket.

Later, the package was copied to Jaunty which incorrectly caused the Intrepid bugtask to be closed.

This is because the code that closes bugs in scripts/processaccepted.py generates the bugtask's sourcepackage by calling SPR.sourcepackage. That code is assuming the series comes from the spr.upload_distroseries.

Instead, the series should come from the copied publication record and the bugtask sourcepackage should be generated with series.getSourcePackage()
