Bug 14264: Fix export of late orders when translated

Bug 7298 tried to fix this issue, but it was not correct.
We have 3 files in acqui/csv:
basketgroup.tt, basket.tt and lateorders.tt
The first 2 don't contain translatable string, and are not modified on
translating the templates (`translate install`)
On the contrary, lateorders.tt has some strings to translate ('Author:',
'Published by:', etc.). After being translated, all carriage returns
between TT tags are removed.

Test plan:
1/ choose a language and update + translate the templates
for instance:
  cd misc/translate;
  ./translate update es-ES; ./translate install es-ES
2/ Go to acqui/lateorders.pl using this language
3/ Generate a csv for 1+ late orders and confirm the first line only
contains the headers.
