Fix parsing error in spl question.

Newlines not permitted at the start of questions in the parsing rules, this commit should fix an error in the syntax of one question that was stopping deployment.

We should probably talk about either permitting new lines like this and/or trying to preload all the flows as part of the build step so things like this can be caught before we need to deploy. It wont be caught in development as flow preloading is turned off.
