Bug 18675: Translatability: Get rid of [%% in translation for csv-profiles.tt

Bug 18675: Translatability: Get rid of [%% in translation for csv-profiles.tt

Translation tool for file csv-profiles.tt picks following line:
%s [%% IF csv_profile.encoding == encoding OR NOT csv_profile AND encoding == 'utf8' %%]
It is is due to a line break inside a template directive. This patch removes it.

To test:
- Verify that code change makes sense
- Apply patch
- Verify that csv exports behave as before
