Add a conformance test for removing a pipeline layer

Browse source 
The test creates a pipeline with two layers which add two different
color constants together and then tries various combinations of
removing the layers and checks that it gets the right color.

Currently this is failing if a pipeline is copied and then a layer is
removed from the copy.
