JIRA: https://jira.spring.io/browse/INT-4487
Currently the `AbstractReplyProducingMessageHandler` applies advices
only in the `afterPropertiesSet()` phase.
When we use bean references for `MessageHandler`s in Java DSL, the
`.advice()` provided in the flow definition is not applied to the
`AbstractReplyProducingMessageHandler`.
* For consistency with the endpoint configured by the DSL definition,
override and reconfigure advices in the `AbstractReplyProducingMessageHandler`
bean reference during DSL parsing and processing.
Fix `TwitterSearchOutboundGatewayParserTests` for the proper assert
