[CrOS Network] Do not display network icon if there's no network state

This CL fixes the bug where an unnecessary black square is seen when
user click on 'Forget' option in Chrome OS settings page. The bug is
introduced by CL:
https://chromium-review.googlesource.com/c/chromium/src/+/3029745.
This is because when there's no network state, it will fill in the
entire icon div with the background color, so change to hide the icon in
this case.

Logo Chromium

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.

The project's web site is https://www.chromium.org.

To check out the source code locally, don't use git clone! Instead, follow the instructions on how to get the code.

Documentation in the source is rooted in docs/README.md.

Learn how to Get Around the Chromium Source Code Directory Structure .

For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.
