Rename AutoConfigureReportTestExecutionListener to
SpringBootDependencyInjectionTestExecutionListener and ensure that it
replaces any existing DependencyInjectionTestExecutionListener.

Prior to this commit the registration of two DependencyInjection
listeners would cause @PostConstruct methods on tests to be called
twice.

In order to allow the standard DependencyInjectionTestExecutionListener
to be removed a new DefaultTestExecutionListenersPostProcessor interface
has been introduced.

Fixes gh-6874
