fix(http): panic when responding to a closed conn (#12216)

Our oneshot receiver in `HyperService::call` would unwrap and panic, the `.await` on the oneshot receiver happens when the sender is dropped.

The sender is dropped in `op_http_response` because:
1. We take `ResponseSenderResource`
2. Then get `ConnResource` and early exit on failure (conn already closed)
3. The taken sender then gets dropped in this early exit before any response is sent over the channel

Fallbacking to returning a dummy response to hyper seems to be a fine quickfix
