Description:

After the 4.4.0 update, outgoing integrations no longer seem to accept the response text. I have created an extremely simple outgoing integration that will respond with {"text":"test"} to any request, but rocket.chat will not post that message into the channel. When I try to debug this by viewing history, I get a blank page. It seems any integration that has more than 0 history will respond with a blank page this way. This is the error I get in console when attempting to open the history: TypeError: u is not a function

Steps to reproduce:

1. Create an outgoing WebHook Integration
2. Point it to a URL that responds with {"text":"test"}
3. Trigger the outgoing WebHook
4. Observe that the WebHook receives the request, responds with a 200, but nothing appears in the channel

Expected behavior:

Taking my response and posting it in the channel

Actual behavior:

Nothing happens
