[FIX] sale: allow duplicate SO from other company
[FIX] sale: allow duplicate SO from other company

- In some cases (record rules modified to allow access to multi company
  SO) the duplication of a quotation isn't possible if the quotation is
  set on a company than the user trying to duplicate it.

  This is due to a computed field that tries to access the order's
  company currency.
