Tests: unbreak tests with dynamic certificates on stable.
In 74cffa9d4c43, ticket based session reuse is enabled in addition to
using a shared SSL session cache. This changed how a session can be
resumed in a different server:
- for a session ID based resumption, it is resumed in the same context
- when using session tickets, a key name is also checked for matching
- with a ticket callback, this is skipped in favor of callback's logic
This makes 'session id context match' tests fail with session tickets
on stable since ticket key names are unique in distinct SSL contexts.
On the other hand, tests pass on 1.23.2+ due to automatic ticket keys
rotation that installs ticket callback, and using a common shared SSL
session cache.
