"UndefVarError: @suppress not defined", when used with SafeTestsets

[nguiard]

Hi, thanks for this library!

Using @suppress in a @safetestset block triggers an "UndefVarError: @suppress not defined". Minimal example, a package with just Supppressor and SafeTestsets installed, test/runtests.jl:

using SuppressorBug
using Test
using SafeTestsets

@safetestset "SuppressorBug.jl" begin
    using Suppressor
    @suppress println("Toto")
end
