fix(client): fix js compatible with multi args in online eval

[jialeicui]

Description

The problem:

The reason:

gradio will make sure the return value is a list

dependencies.forEach((d) => {
if (d.js) {
	try {
		d.frontend_fn = new AsyncFunction(
			"__fn_args",
			`let result = await (${d.js})(...__fn_args);
			return ${d.outputs.length} === 1 ? [result] : result;`
		);
	} catch (e) {
		console.error("Could not parse custom js method.");
		console.error(e);
	}
}
});

ref: https://github.com/gradio-app/gradio/blob/v3.15.0/ui/packages/app/src/Blocks.svelte#L67

gradio expands the payload.data.concat(output_data) as fn_args

So, when there is only one output, nothing wrong, and when there are multiple outputs, we return the wrong response.

if (frontend_fn !== undefined) {
	payload.data = await frontend_fn(payload.data.concat(output_data));
}
