Bug 20084: Fix Industrial2of5 and COOP2of5 patron card layouts

== Test plan ==
This is an oversimplification of a full patron card setup used in production.

1. Create a batch with 1 patron
2. Create a layout and set
     the name
     "Print card number as barcode"
     "Barcode type:" to "Code 39"
3. Create a card template without filling anything
4. Export the batch using the layout and template
5. You should have a white page with a barcode
     And no errors in the relevant log file
     This show that this setup isn't completely bogus
     (although Code 39 is the only type working...)
6. Layout: set "Barcode type:" to Industrial2of5
7. Export the batch
8. You should have a white page with no barcode
     And errors in the relevant log file
     "Invalid Characters"
     This is the bug.
9. Layout: set "Barcode type:" to COOP2of5
10. Export the batch
11. You should have a white page with no barcode
      And errors in the relevant log file
      "Invalid Characters"
      This is the bug.
12. Apply this patch
13. Retry with both non-working patches
    1. You should have a white page with a barcode
    2. And no errors in the relevant log file
