[IMP] stock: choose destination wizard

Purpose : during a transfer, if some move lines have different
destination locations and the user click on 'put in pack' button, an
warning is triggered. This message, saying : 'You cannot put in the same
pack move lines having different destination location', is replaced by a
wizard allowing the user to choose a unique destination location. This
location will be set as location_dest_id on all transfer's stock move
lines. After that, the wizard calls again the _put_in_pack() method
where all the logic remains the same.
