Option None Element crash the Renderer on Fullstack Serve direct access

[gusinacio]

Problem

When you return a rsx!{} or a None as an Element, the renderer crashes with the following logs:

[INFO] dioxus_fullstack::render - Suspense resolved
thread 'tokio-runtime-worker' panicked at /Users/gustavoinacio/.cargo/git/checkouts/dioxus-5df58c476196bcfb/55d1f83/packages/ssr/src/renderer.rs:129:38:
not yet implemented: generally, scopes should be sync, only if being traversed

called `Result::unwrap()` on an `Err` value: RecvError(())

If you access another page, then the page with None element, it renders correctly.

Steps To Reproduce

Steps to reproduce the behavior:

• Create a component that returns None:

  #[component]
  pub fn Test() -> Element {
  None // it can be rsx!{}
  }

• Add the element to a page (via Router)
• Access the page directly

Expected behavior

When accessing a None element, it should not display anything and it should not crash.
