Optimize the lesson query #8

We should optimize the index query to return just the lesson with the instrument name string and the section name string for the current objective. Something along the lines of

select lessons.*, section.current from lessons inner join (select current, lesson_id from sections) as section on section.lesson_id=lessons.id and section.current == true;

Perhaps using Arel if it makes sense.
