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 😸
