INT-4389: Default to SimpleSeqSizeReleaseStrategy (#2444)

* INT-4389: Default to SimpleSeqSizeReleaseStrategy

JIRA: https://jira.spring.io/browse/INT-4389

An `AbstractCorrelatingMessageHandler` fallback to the
`SimpleSequenceSizeReleaseStrategy` when `releaseStrategy` isn't
provided.

* Make `ReleaseStrategyFactoryBean` to fallback to the
`SimpleSequenceSizeReleaseStrategy` for consistency.

* * Fix `ResequencerParser` to fallback to the null `releaseStrategy`.
This way a subsequent `releasePartialSequences` will set a
`SequenceSizeReleaseStrategy` as a default one

* * Fix `BarrierMessageHandler` to populate a default `CorrelationStrategy`

* * More polishing to `BarrierMessageHandler`
