Migrate ReturnAddressTests to JUnit 5

Looks like `ApplicaitonContext.stop()` is note called on `close()`.
This might cause an `OutOfMemoryError` on the CI

* Use Spring context configuration for the test environment

Author: artembilan

spring-integration-core/src/test/java/org/springframework/integration/endpoint/returnAddressTests.xml renamed to spring-integration-core/src/test/java/org/springframework/integration/endpoint/ReturnAddressTests-context.xml
