Request for head-route does not work if AutoHeadResponse is installed

[MikeMitterer]

Ktor Version and Engine Used (client or server and name)
1.3.2

Describe the bug
head route does not resolve as expected

To Reproduce
install(AutoHeadResponse)

     route("/api") {
            head("/v1") {
                call.respond(HttpStatusCode.NoContent)
            }
        }

curl -I http://0.0.0.0:8080/api/v1 fails with 404

Expected behavior
curl should see a 204

I found out that this happens only if AutoHeadResponse is installed - I'm not sure if this is expected behaviour or not but at least it should be documented

Hi @MikeMitterer, I prepared the fix. Currently, it's on review.
