robustify 'find axis' logic:
- make sure that graphs with only orphan cartesian are considered 'cartesian' - make sure that axes associated with GL2D traces aren't considered 'cartesian' - by making layout with { xaxis: {}, yaxis: {} } a 'hasCartesian' plot, deleting the last cartesian trace retains the axes.
