JIRA: https://jira.spring.io/browse/INT-3823
The test stops the endpoint.
The previous poller thread can 'steal' the `input` message, but since
it is interrupted, it can't send the message to the `publishedChannel`.
Add logic to wait until the previous poller has been interrupted in `receive()`.
Increase the endpoint `receiveTimeout` to ensure the thread will be interrupted.
Bump SF Version to 4.2.3
Remove `TRACE` logging from the `EnableIntegrationTests` since we have the fix already
Make some optimization around `@DirtiesContext`
