Fix foreachprogress returning early

[brendanjohnharris]

In the current version, foreachprogress exits without doing or showing a thing.
It looks like a stray return is the culprit?
This PR deletes it 🕺

As a simple example:

x = zeros(10)
foreachprogress(eachindex(x); description = "Working...") do i
    @info i
    x[i] = 1
    sleep(0.1)
end
sum(x)

Current behavior: prints nothing, returns 0
New behavior: prints @info and ProgressBar, returns 10

That looks good, thanks for the fix.
