Provide option to draw graticule, or fail gracefully?

[cpsievert]

There are projections where plot() still produces (an arguably wrong) result when a st_graticule() fails. Would it make sense to replicate that behavior of failing "gracefully"? Or maybe even something like coord_sf(graticule = FALSE) since it might also help out with #2071?

library(sf)
library(mapdata)
w <- st_as_sf(maps::map("world", plot = FALSE, fill = TRUE))
wt <- st_transform(w, "+proj=aea +lat_1=55 +lat_2=65 +lat_0=50 +lon_0=-154 +x_0=0 +y_0=0 +ellps=GRS80 +towgs84=0,0,0,0,0,0,0 +units=m +no_defs")
plot(wt)

 st_graticule(wt)
#> Error code: 6
#> Error in CPL_transform(x, crs$proj4string, crs$epsg) : OGR error

ggplot() + geom_sf(data=wt)
#> Error code: 6
#> Error in CPL_transform(x, crs$proj4string, crs$epsg) : OGR error

This now works with sf devel (and probably also 0.5-1):
