Add tests for profile enforcement

Now all checks related to profile are covered in:
- verify_with_profile()
- verify_child()
- verify_top()
(that's 10 lines that were previously not covered)

Leaving aside profile enforcement in CRLs for now, as the focus is on
preparing to refactor cert verification.
