Internal interception on a mock changes the DefaultValue property

[vladonemo]

Let's consider this use case:

public void DefaultValueIsNotChangedWhenPerformingInternalInvocation()
{
	var mockBar = new Mock<IBar> { DefaultValue = DefaultValue.Empty };
	var mockFoo = new Mock<IFoo>();
	mockFoo.SetupSet(m => m.Bar = mockBar.Object);
	Assert.Equal(DefaultValue.Empty, mockBar.DefaultValue);
}

The SetupSet changes the DefaultValue of the mockBar to DefaultValue.Mock.

I'm submitting a PR shortly.
