The logic in the `FluxMessageChannelTests.testFluxMessageChannelCleanUp()`
relies on the `finishLatch.countDown()` which happens before we
release the lock for a group in the aggregator.
So, when we call a `destroy()` as the next statement, we interrupt
the lock instead of unlocking.
This cause a race condition in the Reactor's `Sink` to terminate properly
* Expose `CorrelationHandlerSpec.releaseLockBeforeSend()` and set it to `true`
in the test to properly unlock before we call `finishLatch.countDown()`
* Deprecate a couple introduced before options in favor of their variants
with `set` prefix
* Fix new Sonar smells
