crypto/tls: fix test data generation

- Multiple GetCertificate tests shared the same name and were
  overwriting each other, each test now has a unique name.
- expectAlert was not implemented in the data updater, the single
  test that used it has been replaced with a ClientHello failure
  test.

Fixes #10470
