Fullstack + WASM split hydration issues

**Problem**

When enabling both the `fullstack` and `wasm-split` features, hydration does not work as expected.

Using the default generated project:

- If no extra flags are passed to the CLI, `__wasm_split.js` is not generated, and the echo server function does not load. The blog page navigation requests new pages from the server, and continues to function.
- If the `--wasm-split` CLI flag is supplied, then hydration fails in the browser with the following error:

wasm-bindgen: imported JS function that was not marked as `catch` threw an error: Cannot read properties of undefined (reading 'toString')

```
patch_console.js:1 wasm-bindgen: imported JS function that was not marked as `catch` threw an error: Cannot read properties of undefined (reading 'toString')

Stack:
TypeError: Cannot read properties of undefined (reading 'toString')

The cause of the stacktrace appears to be: the `data-node-hydration` ID is greater than the number of nodes being passed to the `hydrate` function.

If I manually alter the `dioxus-interpreter-js/inline0.js` file being served to return early if the node ID does not exist e.g.:

...}hydrate_node(hydrateNode,ids){let split=hydrateNode.getAttribute("data-node-hydration").split(","),id=ids[parseInt(split[0])];if (!id) return;...

```diff
hydrate_node(hydrateNode: HTMLElement, ids: { [key: number]: number }) {
const hydration = hydrateNode.getAttribute("data-node-hydration");
const split = hydration!.split(",");
const id = ids[parseInt(split[0])];
+ if (!id) return;

this.nodes[id] = hydrateNode;
```

, then the console errors go away, the echo server function works as expected, and the blog navigation is handled client-side. I can see from the network trace that the WASM has been split, and multiple modules are being loaded.

_However_, a non-hydrated duplicate of the home page is shown below the working, hydrated version:

**Steps To Reproduce**

Steps to reproduce the behavior:

- Create a new project via `dx new`:
```
> dx new foo ╯
✔ 🤷 Which sub-template should be expanded? · Bare-Bones
✔ 🤷 Do you want to use Dioxus Fullstack? · true
✔ 🤷 Do you want to use Dioxus Router? · true
✔ 🤷 Do you want to use Tailwind CSS? · false
✔ 🤷 Do you want to include prompts for LLMs? · false
✔ 🤷 Which platform do you want DX to serve by default? · Web
```
- Add the `wasm-split` feature to `dioxus` in `Cargo.toml`:
```toml
dioxus = { version = "0.7.0-rc.0", features = ["router","fullstack","wasm-split"] }
```
- Serve with the `wasm-split` feature:
```
dx serve --web --wasm-split
```

**Expected behavior**

A single, hydrated copy of the app should be rendered without errors.
