The cert-request command used to accept CSRs that had extra data surrounding the PEM data, e.g. commentary about the contents of the CSR. Recent commits that switch to using python-cryptography for cert and CSR handling broke this. Our acceptance tests use such CSRs, hence the tests are now failing. To avoid the issue, freshly encode the python-cryptography CertificateSigningRequest object as PEM. This avoids re-using the user-supplied data, in case it has extraneous data.
