how about removing function last_plot?

plotly depends on ggplot2 which alreadly has loaded function last_plot(), so, maybe we can throw it away as ggridge did

Brief description of the problem

library(plotly)
#> Loading required package: ggplot2
#> 
#> Attaching package: 'plotly'
#> The following object is masked from 'package:ggplot2':
#> 
#>     last_plot
#> The following object is masked from 'package:stats':
#> 
#>     filter
#> The following object is masked from 'package:graphics':
#> 
#>     layout
plotly::last_plot
#> function () 
#> .store$get()
#> <bytecode: 0x7f9575ad7558>
#> <environment: namespace:plotly>
ggplot2::last_plot
#> function () 
#> .store$get()
#> <bytecode: 0x7f9575ad5cd8>
#> <environment: namespace:ggplot2>

Comienza comparando los puntos de entrada públicos plotly::last_plot y ggplot2::last_plot que se muestran en el informe y, después, inspecciona cómo plotly expone o prueba last_plot. Determina el comportamiento existente del paquete y la cobertura de pruebas antes de eliminar el duplicado; se considera terminado cuando plotly ya no oculta el last_plot de ggplot2 sin romper el uso compatible.
