Minor bugfix: If you pass an object for a line-type feature, the data attribute ends up being converted in to a triply-nested array. Passing in the same feature-spec again won't draw that feature (because the data[0][0] is an array, rather than the first {x:1, y:0.5} pair). This PR changes the point at which the extra layer of array is added (i.e. it doesn't change the input data in to a form that won't render).
