NetworkSettings: Don't assert when there are no network adapters

Browse source 
NetworkSettings normally filters out `loop` when populating its list of
adapters. However, when checking if there aren't any adapters it did
not take this into account. This causes it to crash later when trying
to set the selected index of an empty combo box.

This moves the check for no adapters to after filtering the list, so
that shows the error message and exits.
