createMenuItems() is not reactive

[Artur-]

Describe the bug

createMenuItems() uses data from window.Vaadin.views to render the menu but there is no mechanism that would update the menu hwen window.Vaadin.views changes.

Expected-behavior

Like everything else in React, the menu items should be reactive

Reproduction

window.Vaadin.views["/hello"]={flowLayout: false, lazy:false, loginRequired: false, menu: {title: null},params:{},register:false,rolesAllowed:null, route:'hello', title: 'Hello new view'}

The item appears in the menu on the next re-render, e.g. when navigating. It should appear immediately
