Default for spring.kafka.listener.missing-topics-fatal is no longer aligned with Spring Kafka's default

(Also Boot 2.2).

We changed the default in spring-kafka to false in 2.3.4.

This property was added in S-K 2.2 with default true but this caused too many problems for the community.

Hi, I'm looking to start contributing to OSS and this looks like a good place to start, is this up for grabs?

[snicoll]

Yes. We’d need a test to assert the default is consistent. Thanks for the offer!

Thanks @snicoll , I'll start working on it. 👍
