[501864] Do not add refined diffs to conflicts of refining diffs
Refined diffs should not be added automatically to the conflicts of its refining diffs. In case of multiple conflicts, the refined diff would otherwise randomly end up in the last one to which it has been added. This change also adapts the test cases and improves the MultiplicityElementChangePostProcessor to be more efficient. Note that I had to ignore the AdditiveMergeDiagramTests as they seem to fail after this change. Unfortunately, I don't see why. I assume that this is because previously the AdditiveConflictMerger handled the refined diffs if one of its refining diffs was conflicting, but doesn't anymore after this change.
