Make sure that the currently-set language is the one that shows on the left sidebar if no language  preference exists.

Some students were confused by the display on the sidebar when it would say 'English' even if the text was in another language. This should fix the problem.

Right now we're operating under a "we cannot un-release a language as that breaks a promise we have" type mentality. However, I think it might be worth adding in the check that Steve suggests. It's safer in the off chance we do have to un-release a language, and just makes more sense.
