Fix some multiple choice levels showing the question twice in the level details dialog

[bethanyaconnor]

Fixes some multiple choice levels showing the question multiple times. This was happening because question and get_question_text were sometimes the same (but sometimes different which is why I didn't catch this initially). This new code models how the haml displays this info, first displaying content in the content{1-4} fields, (here from here) and then displaying localized_questions[0]["text"] here. Match levels use localized_questions for the answers, which is out of scope of this PR.
