Bean override with REPLACE_OR_CREATE_DEFINITION and byType lookup fails if no match is found

[snicoll]

Consider the following scenario:

@SpringJunitConfig
public class MyTest {

  @MockitoBean
  private ExampleService service;

}

With zero ExampleService in the context. MockitoBean has a REPLACE_OR_CREATE_DEFINITION strategy, which means it should create a (mock) bean for that type if none is found.

Right now it fails as:

Caused by: java.lang.IllegalStateException: Unable to select a bean definition to override: found 0 bean definitions of type org.springframework.test.context.bean.override.example.ExampleService (as required by annotated field 'ZeroCandidatesTestCase.example')

There's even an integration test to assert the (faulty) scenario.
