Http Handler response hangs indefinitely when handler returns `int` value

[nkosi23]

Describe the bug
In F#, when an http handler returns an int value (whether int or Task), the body of the handler is correctly executed but no response is ever returned to the client :

• the browser client is waiting for the response to complete,
• while in postman i see that an empty response is returned and it complains that the response is not valid.

The problem does not occur if i cast the value to decimal.

To Reproduce

[<WolverinePost("/api/test")>]
let myTestHandler() =
     let myValue : int = 5
     myValue

Expected behavior
A response is returned to the client.

@nkosi23 This scenario is tested in the codebase. Returning an int would just set the HTTP status code to that value. I'm not sure this is a valid usage.

@jeremydmiller Oh now that you say it that makes sense, i even have vague memories of seeing something like that in the docs.

Well to be fair, after all the time i've spent using Wolverine, it was the first time I needed to return a raw int. I'm not sure having a special handling for this scenario would be worth the trouble.

What i do fairly frequently is returning a raw Guid or string after a document has been created, so maybe folks needing to return an int id may bump into this, but i'd say it's unlikely that someone using the CritterStack would use int as an id type.

Anyway, I don't know if i should close this ticket, what are your thoughts?

I'm honestly just beating this w/ extra docs
