Bug#913913: security.debian.org: bullseye security updates may be silently skipped on systems using apt pinning

[Piotr Engelking <inkerman42@gmail.com>]

Package: security.debian.org
Severity: normal
Tags: security

With the release of buster, testing security updates switched from
Suite: testing to Suite: testing-security. This silently breaks
security updates on systems using apt pinning to elevate the priority
of testing packages.

Also, bug #913913 makes this already non-obvious configuration problem
even harder for users to discover and to correctly fix.

Please consider reverting this change.
