[FIX] stock: description delivery slip

Before this commit, the description of the move was displayed on the
Delivery Slip report, even if the description is exaclty the same as the
product name (which is the case by default).
Now, as it's somehow ugly to have the repetition, they will not display
the description if it's the same as the product name.
