Default dist formatter doesn't work

[mitchelloharawild]

This should format the distributions with ?.

library(distributional)
new_dist(x = 3, class = "dist_test")
#> <distribution[1]>
#> Error in vapply(x, format, character(1L), ...): values must be type 'character',
#>  but FUN(X[[1]]) result is type 'list'
