Bug 26340: When printing labels from a barcode range, keep zero padding

Bug 26340: When printing labels from a barcode range, keep zero padding

TEST PLAN:

1. Go  Tools > Label creator
2. Click +New -> Barcode range
3. Print barcode range with zero(s) in the start (Ex. from 00011881 to 00012000 )
4. Select a template to be applied:: Code à barre 48467
Select a layout to be applied: Code à barres
5. Export
6. Open PDF

The prefix is not displayed. We should see 00011881 on the labels, but we see 11881, 11882, ... without zeros in the start of labels.
This patch fix it.
