When a command returns an empty array in JSON it should not be null

[jerome-quere]

When using JSON output with a command that returns an empty list we should have [] not null
example

$> scw instance volume list volume-type=b_ssd
null

It may be possible with some dirty hacks though

Something like:

    var output string
    buff := bytes.NewBufferString(output)
    err = json.NewEncoder(buff).Encode(data)
    if err != nil {
        return err
    }
    if buff.String() == "null\n" {
        _, err = o.Writer.Write([]byte("{}\n"))
        return err
    }
    _, err = o.Writer.Write([]byte(buff.String()))
    return err

But it's ugly 😅

We can use an if before calling JSONEncode.
