[FIX] mrp: print barcodes

- Create a product A with a barcode, UOM as 'Unit(s)' with a BOM
- Create a MO for A with more than one unit, validate
- Print the 'Finished Product Label (PDF)'

A single label is printed for all units, although it is not logical: a
label should be printed for each unit, as already done for the Zebra
labels.

In case the product UOM is 'Unit(s)', we print a label per unit. At the
same time, we remove useless horizontal lines.
