GH-195: Fix cafe-dsl for missed subscriber

Browse Source 
Fixes https://github.com/spring-projects/spring-integration-samples/issues/195

After some Java DSL modification to request an explicit subscriber for replies
into a main flow from the `route()`, the `cafe-dsl` has stopped to work

* Remove redundant `defaultOutputToParentFlow()` since it doesn't bring any
value into a flow logic
* add `bridge()` into all the route sub-flows as a thirds subscriber to
make an explicit reply into a main flow after delay and logging
