default value in plugin schema only has effect if plugin form is changed

[macrozone]

Describe the bug

default: "xxx" in a schema of a plugin does show that value in the generated form, but unless any property is changed, it won't update the node

To Reproduce

e.g

import { createContentPlugin } from "@react-page/create-plugin-materialui";
import React from "react";

export default createContentPlugin<{
  title: string;
}>({
  Renderer: ({ state }) => {
    return <SomeComponen title={state.title} />;
  },
  name: "someplugin",
  version: "0.0.1",
  text: "Some plugin",
  schema: {
    required: ["title"],
    properties: {
      title: {
        type: "string",
        default: "Some Default Title",
      },

    },
  },
});

Expected behavior

it should add the plugin with all default values

[macrozone]

fixed!
