Fix error response when `:body` is `stream`

[nenadalm]

Hi. First response code and headers are written: https://github.com/macchiato-framework/macchiato-core/blob/f21bddc621745696b85e5fa97870f6fe913fcf1a/src/macchiato/http.cljs#L102

then stream is piped into node response: https://github.com/macchiato-framework/macchiato-core/blob/f21bddc621745696b85e5fa97870f6fe913fcf1a/src/macchiato/http.cljs#L96

then if error occurs: https://github.com/macchiato-framework/macchiato-core/blob/f21bddc621745696b85e5fa97870f6fe913fcf1a/src/macchiato/http.cljs#L95 response code and headers are written again: https://github.com/macchiato-framework/macchiato-core/blob/f21bddc621745696b85e5fa97870f6fe913fcf1a/src/macchiato/http.cljs#L110

which causes nodejs crashing with: Error [ERR_HTTP_HEADERS_SENT]: Cannot set headers after they are sent to the client and streamed file seems to be downloaded properly in browser (what was sent until the error is in the content and there is no hint that something failed)

With this fix request is aborted and file shows Network error in browser which is probably how it should be.
