Bug 10935: fix breakage of CSV acq exports when using a non-English translation

Bug 10935: fix breakage of CSV acq exports when using a non-English translation

To reproduce:
- cd misc/translator
- ./translate update LANG
- ./translate install LANG
- go to the Koha mainpage and change the language.
- go to acqui/basketgroup.pl?booksellerid=XX and try to export a
  basketgroup.
The headers is followed by the first basketgroup information. There is
no carriage return.

It looks like it is caused by a routine used by the translator script
(TmplTokenizer::string_canon).

To test this patch:
- apply it
- cd misc/translator
- ./translate -f update LANG
- translate headers in your po file
- ./translate -f install LANG
- go to acqui/basketgroup.pl?booksellerid=XX and try to export a
  basketgroup.
- verify that the csv looks good now.
- same thing for basket.

Good idea and seems to work - just fixing a small glitch
with the first entry of the list in a follow-up.
