AbstractDelegatingMutablePicoContainer addComponent() unwraps the delegate picoContainer.

@Test
public void testAddComponentReturnsOutermostContainer()

{ MutablePicoContainer outer = createPicoContainer(null); MutablePicoContainer resultOfAddComponents = outer.addComponent(A.class) .addComponent(B.class); assertTrue(resultOfAddComponents == outer); }

Working on a fix, but current fix breaks some other tests. In process of investigating.
