Is this a new UI feature for popping up detailed network view when wifi is
changed to enabled state, or it just matches an exisiting UI feature?

This replaces TrayNetwork::OnWillToggleWifi() which will become deprecated. I
added a test in OnWillToggleWifi() to ensure that we don't call this twice.
