Same fixes for the purchase scope
1) Do not overwrite lines description if the line was not modified
2) Correctly recompute prices/sellers on quantity change.
When no new line was added to the PO through the matrix, the
prices/sellers were not recomputed, even if the qty was modified for
some products.
