Incorrect path of shadow-layout.html in Step 4: Scaffolding the signed-in view

[abdshomad]

The tutorial instruct to write:
<link rel="import" href="../bower_components/paper-styles/classes/shadow-layout.html">
<link rel="import" href="../bower_components/paper-toggle-button/paper-toggle-button.html">

The above is correct when we are in sub-folder (eg: "steps")

Because we are still working in the root folder, the import should be changed to omit "../" such:
<link rel="import" href="bower_components/paper-styles/classes/shadow-layout.html">
<link rel="import" href="bower_components/paper-toggle-button/paper-toggle-button.html">
