Remove listenerScope field override in annotation processors

This commit fixes the case where SpEL expressions using the `__listener.`
bean ref were failing due to the concrete impls of the
`AbstractPulsarAnnotationsBeanPostProcessor` hiding/overriding their
parent's `listenerScope` field by removing the `listenerScope` field from
the following concrete impls:
- PulsarListenerAnnotationBeanPostProcessor
- ReactivePulsarListenerAnnotationBeanPostProcessor

Fixes #1169
