Remove default values from config for network adapters

[jboddey]

Steps taken

1. Install the application for the first user flow
2. Open the application

Actual result:

• The step 1 of the user flow is not shown. The callout to configure settings is shown in red and step 2 to create device

The fake intf are in the config file by default in the package.

Expected: the step 1 is shown in blue to navigate the user through the first flow. The intf in the config file should have empty values.
