Duplicated use of similar functions

Lines 945-952 of `path2rap()`:

```r
    if (!use_codification) {
      lhs %<>% translate_objects(within_rule = TRUE)
      rhs %<>% translate_objects(within_rule = TRUE)
    }
    if (!use_codification) {
      lhs %<>% translate_side_labels()
      rhs %<>% translate_side_labels()
    }
```

That's clearly **heresy**.

Please, fix that in order to better understand the code.
