Ability to supply `figure` without `data`

[chriddyp]

v0.22.1 introduced a bug:

+ if (intersection(
+ pluck('type', figure.data),
+ ['candlestick', 'ohlc']).length
+ ) {
+ PlotMethod = Plotly.newPlot;
+ } else {
+ PlotMethod = Plotly.react;
+ }

now, if figure.data is undefined, the pluck('type', figure.data) fails. I believe that we should be able to fix this with just a R.has('data', figure) check. We should add some tests that supply figure as None, {}, {'layout': {}}, and {'data': []}

@valentijnnieman - Could you grab this one this week? I've seen a few users report this issue in the forum, seems like it'd be an easy win 😸
