Fix to allow spy() with implementations (not interfaces) - IllegalStateException: Injecting null

[rbygrave]

Where Grinder is an implementation class and not an interface

  @Test
  public void withMockitoSpy_postLoadSetup_expect_spyUsed() {

    try (BeanContext context = new BootContext()
      .withSpy(Pump.class)
      .withSpy(Grinder.class) // HERE
      .load()) {

      ...

      CoffeeMaker coffeeMaker = context.getBean(CoffeeMaker.class);
      coffeeMaker.makeIt();

      ...

      Grinder grinder = context.getBean(Grinder.class);
      verify(grinder).grindBeans(); // throws IllegalStateException
    }
  }

java.lang.IllegalStateException: Injecting null for org.example.coffee.grind.Grinder when creating class org.example.coffee.CoffeeMaker - potential beans to inject: []

Tested with 1.7-Snapshot. Still failing with "NotAMock"

Are you able to produce a test case?

I will try my best :-)
