Pre-defined colorscales has no effect on heatmaps

[priyatharsan]

The heatmap/heatmapgl plots has no effect from the predefined color-scales such as "Greys", "Picnic", "Rainbow", "Red", etc..

However, when specifying the RGB matrix manually to the color-scale changes the color.

p <- plot_ly(z = zdata, colorscale = "Greys", type = "heatmap")
