Should allow to send message without payload.text

[shamasis]

This is a valid usage to send with only attachments and no text.

Line 13 of slack.js should be

if (!message.text && !Array.isArray(message.attachments)) {

[shamasis]

Currently you can bypass that check by providing text as

{
      toString: function () { return '' }
}
