Forum channels still use payloads from early beta

[Lulalaby]

Problem

Discord informed us that our payloads for post creations in forum channels are invalid.

Before we could specify the message directly in the root object as content, as well as other fields.

This was changed long ago tho.

	if content:
	payload["content"] = content

	payload["embeds"] = [embed]
	if embeds:
	payload["embeds"] = embeds
	if nonce:
	payload["nonce"] = nonce

	payload["allowed_mentions"] = allowed_mentions

Solution

The inner payload for the message has to be a message payload.

{
    "message": {
        // message object properties
    }
}

Additional

While looking through blame, it came to our attention that there's another problem with a certain route which had a special param before release to test.
The param needs to be removed.
