Tests should wait for the router to complete routing operations

[Artur-]

If you have a TypeScript view in your app, e.g.

    {
        path: 'hello',
        component: 'hello-world-view',
        action: async () => {
            await import('./typescript/hello-world-view');
        },
    },

and you have a test that opens /hello then it would be expected that the test waits until hello-world-view has been imported and rendered before proceeding. Right now, it proceeds as soon as the index page has been rendered and router just started fetching hello-world-view
