[505986] Fix decorator on conflicting refined diffs

Refined diffs that are not in a conflict but have at least one of their
refining diffs (recursively) in a real conflict should have the
conflicting decorator.
They should have the pseudo conflict decorator if all their atomic
refining diffs are in pseudo-conflict.
