[FIX] delivery: delivery slip hs code
[FIX] delivery: delivery slip hs code

The variable that was setting the has_hs_code is set in the array
'stock_move_table' which has a t-if on the state to check it's not done,
so if the state is done, the variable is no set and hs_code never shown.

So we've put the variable in the begining of the report.
