Add ability to add to beginning of TestExecutionListener list in TestContextManager [SPR-7595]

[spring-projects-issues]

Mark Pollack opened SPR-7595 and commented

The Spring AMQP project has a need to start an external process (the rabbitmq broker) before any of the applications contexts are bootstrapped. The method registerTestExecutionListeners only allows adding to the end of the execution listener list.

See org.springframework.amqp.rabbit.test.SpringRabbitJUnit4ClassRunner.createTestContextManager for brute force reflection workaround.

The TestContextManager is quite closed to extension as well, would be nice to open it up to be more subclass friendly.

I've simply opened up getTestExecutionListeners() to return the actual internal List which allows for iteration as well as modification, since there is no need to be defensive there anyway. As a consequence, simply calling getTestExecutionListeners().add(0, new RabbitTestExecutionListener()) should do the job now.
