Fixing known patches in deleted contexts

When a patch A introduces a vertex in a deleted context, the edges deleting the context may be introduced by a patch B that knows about A, in which case this is not a conflict. Also, this makes this case symmetric with the other (more common) case where a context deletion is applied after the vertex is introduced.
