[Angular] Errors to fix in order to make works Module

[Magicianred]

In the branch feature/frameworkAngular/move-components-into-module I have problem with use of variable from the module and other similar problem.

`Error: src/app/app.component.html:8:25 - error NG8002: Can't bind to 'todos' since it isn't a known property of 'app-todo-list-footer'.

1. If 'app-todo-list-footer' is an Angular component and it has 'todos' input, then verify that it is part of this module.
2. If 'app-todo-list-footer' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of this component to suppress this message.
3. To allow any property add 'NO_ERRORS_SCHEMA' to the '@NgModule.schemas' of this component.

8 <app-todo-list-footer [todos]="todos">
~~~~~~~~~~~~~~~

src/app/app.component.ts:7:16
7 templateUrl: './app.component.html',
~~~~~~~~~~~~~~~~~~~~~~
Error occurs in the template of component AppComponent.`

It is include of #4
