estimate value `NA` when variable is empty for all estimates

[nmercadeb]

When all values of a variable are NA, most estimate functions return NA however min, max and mean don't and this results in warings, see reprex.

Agreed with @catalamarti and @edward-burn to output them as NA and avoid throwing the warnings.
