min and max throw an error if na.rm = TRUE and all values are NA

[gorcha]

From tidyverse/haven#528 - min() and max() throw an error if all values are NA and na.rm = TRUE.
The base R versions return Inf or -Inf respectively.

They should possibly return NA instead of Inf/-Inf, see #1004.

min(NA_real_, na.rm = TRUE)
#> Warning in min(NA_real_, na.rm = TRUE): no non-missing arguments to min;
#> returning Inf
#> [1] Inf
vctrs:::min.vctrs_vctr(NA_real_, na.rm = TRUE)
#> Error in idx[[1]]: subscript out of bounds

max(NA_real_, na.rm = TRUE)
#> Warning in max(NA_real_, na.rm = TRUE): no non-missing arguments to max;
#> returning -Inf
#> [1] -Inf
vctrs:::max.vctrs_vctr(NA_real_, na.rm = TRUE)
#> Error in idx[[1]]: subscript out of bounds
