Defensive `PersistenceExceptionTranslator` bean retrieval in `PersistenceExceptionTranslationInterceptor` on shutdown

[jhoeller]

Inspired by spring-projects/spring-boot#41092, PersistenceExceptionTranslationInterceptor should defensively retrieve PersistenceExceptionTranslator beans, covering scenarios where the translator has not been initialized before shutdown but a late request starts using the persistence infrastructure during shutdown. It could simply rethrow the original exception as-is in case of a BeanCreationNotAllowedException from detectPersistenceExceptionTranslators.
