Hi Eric,

Was there any particular reason for adding this test? I don't think 
there's any _explicit_ requirement for having tests for both non-PR and 
PR DRBG variants.

In fact, as part of this very comprehensive cleanup, maybe the PR 
variants of the DRBGs should be removed as well? Is anyone actually 
using those? PR variants are (were) registered before the non-PR 
variants, so non-PR was always used by default.

Kind regards,
Joachim
