SpringBoot JooqExceptionTranslator passes null exception to jOOQ when SQLException cannot be translated

Rather than calling ExecuteContext(RuntimeException) with null, we shouldn't call jOOQ at all. This will lead to throwing the original SQLException wrapped in a jOOQ DataAccessException, just as if the JooqExceptionTranslator hadn't been configured.

See https://github.com/spring-projects/spring-boot/pull/25493 for further details.
