JIRA: https://jira.spring.io/browse/INT-3896 Routers created by the `RouterFactoryBean` were not suppressed from being exported by the context exporter when an `IMBE` is present. Move the suppression logic to `postProcessAfterInitialization()` so the annotation on the bean created by the factory bean is detected. The annotation is not detected on the factory bean itself in `postProcessBeforeInitialization()`.
