Hoverinfo doesn't work with plot_geo

[bcdunbar]

hoverinfo doesn't work when used with plot_geo(). If hoverinfo is omitted, default hoveinfo works.

df <-read.csv('https://raw.githubusercontent.com/plotly/datasets/master/2011_february_us_airport_traffic.csv')

# doesn't work
p <- plot_geo(df, lat=~lat, lon=~long, hoverinfo='x')
 
# works with no console errors
p <- plot_geo(df, lat=~lat, lon=~long)

That 'x' should be 'lon', but it still doesn't work because of plotly/plotly.js#2044

This works now
