SpringBoot SpringApplication#addAotGeneratedInitializerIfNecessary is missing tests

Running Spring Boot application with AOT optimizations is broken due to https://github.com/spring-projects/spring-boot/commit/7a5b61fd19e0757d8bf28a3a1a4ef6accfd38261. Here's an example

2022-09-30T10:25:01.712+02:00 DEBUG 88784 --- [           main] o.s.b.d.LoggingFailureAnalysisReporter   : Application failed to start due to an exception

Our build is green so some tests are definitely missing.

I've added a test but I can't replicate the NoSuchMethodError when reverting f0e40bb00dd71bc7cfa4cec8d808ef7afc277871. I'll do a full build then run the samples to see if it still happens.

I can't help thinking that there was somehow a stale Framework jar that didn't have this fix in it.
