Reset plotting layout even when plot.sf fails

[agila5]

Fixes #2519. To be honest, I'm not 100% sure that this is the correct fix and doesn't break anything else 😅

devtools::load_all("C:/Users/andre/Desktop/git-stuff/sf")
#> ℹ Loading sf

nc = st_read(system.file("gpkg/nc.gpkg", package="sf"), quiet = TRUE)
nc[[7]] <- vector("list", 100)
plot(nc[, 1:7])
#> Error in plot.sf(x[, cname], main = cname, pal = pal, nbreaks = nbreaks, : plotting list-columns not supported

# This is now plotted in its own plot
plot(st_geometry(nc))
