[Task] Notifcation context provider is not defined

[tthvo]

Right now, calls to React.useContext(NotificationsContext) will return the default NotificationsInstance because there is no provider in the top of the tree as ServiceContext as below:

<ServiceContext.Provider value={defaultServices}>
    <Provider store={store}>
      <Router>
        <AppLayout>
          <AppRoutes />
        </AppLayout>
      </Router>
    </Provider>
  </ServiceContext.Provider>

I think this is a not an issue that breaks UI but more of a clean up so that the calls are easier to trace.
