Subject: [PATCH] all: adjust nm_utils_is_empty_ssid() to return TRUE for zero
 length SSID

A SSID of zero length, really looks "empty". Let
nm_utils_is_empty_ssid() indicate so too.

This affects some places, that try to guess what a hidden SSID looks
like. In general, it seems that treating a length of zero as empty, is
suitable also then.
