[DELTASPIKE-707] AbstractMockManager does not support interfaces mocked by mockito

Description

Following the manual, I tried to mock EntitityManager in my test class:

@RunWith(CdiTestRunner.class)
public class SomeTest {

    @Inject
    private DynamicMockManager mockManager;

    @Test
    public void mockitoMockAsCdiBean() {
        mockManager.addMock(Mockito.mock(EntityManager.class));
        [...]
    }
}

Unfortunately this doesn't work as AbstractMockManager fails with:

java.lang.IllegalArgumentException: $javax.persistence.EntityManager$$EnhancerByMockitoWithCGLIB$$b065dd9c isn't a supported approach for mocking -> please extend from the original class.
	at org.apache.deltaspike.testcontrol.impl.mock.AbstractMockManager.addMock(AbstractMockManager.java:45)

Following (rather ugly) workaound fixes the problem:

    @Typed(EntityManager.class)
    public static abstract class EntityManagerMockBase implements EntityManager {
    }

mockManager.addMock(Mockito.mock(EntityManagerMockBase.class));

If this problem cannot be solved then the documentation should at least mention that mocking does not work for interfaces and how to work around that.
