julia> unique(AbstractString["a","b"])
2-element Array{String,1}:
 "a"
 "b"

julia> unique(Integer[1,2])
2-element Array{Int64,1}:
 1
 2

Seems like unique should preserve the element type of the input, regardless of whether it's abstract.

Technically breaking, but just mildly so.

Preserve the input element type in unique

Previously the element type of the output was the smallest type that
would fit the union of the input's individual element types. Now the
output has an identical element type to the input. Fixes #22696.
