use default ranks when reorganising rank_address

Browse Source 
When shifting address ranks, the evaluation is always done against
unshifted address ranks on import because the objects we compare against
have not been indexed yet. This changes for updates when the object have
been touched in the meantime. To ensure consistent behaviour across
imports and updates, always use the  unshifted address ranks.
