    network: Fix saving passwords for non-wifi connections
    
    When validating security settings for non-wifi connections, we
    temporarily create a wireless connection. Unfortunately, when this
    connection is destroyed, it'll clear the stored password from the 802.1x
    settings object.
    
    Avoid this by removing the setting before the temporary connection is
    destroyed.
    
    Closes: #337
