No wifi access for guest unless a user is already logged in

[Doug McMahon]

In 16.04.x guest sessions get no wifi access unless a user is already logged in, i.e. one has to open a guest session from a user session.

In 14.04 wifi is automatically enabled for a guest session, in 17.04 a guest needs to enter wifi password & create a keyring.

Test case:
Boot up to a machine using wifi that's password protected, at greeter choose guest.
Once logged in notice nm-applet is running but no connection.
Click on icon, choose a network, click on it.

What happens: nothing

Status changed to 'Confirmed' because the bug affects multiple users.

[Doug McMahon (mc3man)]

Lets call invalid as option to allow all users will allow guest wifi automatically. Whether this should be the default setting would be the only possible bug, not sure that matters
