Code review comment for lp:~maxb/launchpad/use-hashlib

It turns out the entire test is no longer relevant, because it tests for the presence of a bug in apt_pkg.sha256sum, which the first revision in this branch removes all uses of. Hence, the fix is to simply delete the test.

Incremental diff: just the deletion of the entire method lp.archivepublisher.tests.test_publisher.TestPublisher.testAptSHA256

This is ready for re-review and landing now.
