Bug#836342: UDD/testing_autoremovals_gatherer.pl: Version in autoremoval notice may not be version actually checked

["Rebecca N. Palmer" <rebecca_palmer@zoho.com>]

Package: qa.debian.org
Severity: minor
User: qa.debian.org@packages.debian.org
Usertags: udd

When a package has recently migrated, one may receive an autoremoval 
warning that lists the new version of the package, but a problem only 
the old version had.

Example (1.1.2-4 had the problem, 1.1.2-5 doesn't, and is no longer 
listed for autoremoval):

FYI: The status of the beignet source package
in Debian's testing distribution has changed.

  Previous version: 1.1.2-4
  Current version:  1.1.2-5

beignet 1.1.2-5 is marked for autoremoval from testing on 2016-09-04

It (build-)depends on packages with these RC bugs:
