Test fails after 2021-11-27

Error is maybe from tests/certs/test_cert.p12

E           ValueError: Client certificate expired: Not After: 2021-11-27 15:28:58Z Not Before: 2018-11-28 15:28:58Z

requests_toolbelt/adapters/x509.py:139: ValueError

Background:
As part of my work on reproducible builds for openSUSE, I check that software still gives identical build results in the future.
The usual offset is +15 years, because that is how long I expect some software will be used in some places.
This showed up failing tests in our python-requests-toolbelt package build.
See https://reproducible-builds.org/ for why this matters.

Would be good to see this solved in the next 10 months.

This was fixed in #335 which was merged as part of #336. Thanks for the warning, sorry that we did not act on it in time.
