* only relevant when db_mode is PUA_DB_ONLY
* call_id/to_tag/from_tag values can be "", for instance with
  DIALOG_PUBLISH.* records. Then **ALL** records get version
  field update
* update_vesion_puadb() is called from send_publish() and pres->id
  value is valid after a call to get_record_puadb()
