The wlc_clients discovery yielded a Service(item="") when a WLC controller exposed an SSID with an empty name. The agent-based v2 API rejects empty item strings, so discovery crashed with TypeError: 'item' must be a non empty string or ommited entirely, got ''.

Empty SSID names are now skipped so the rest of the WLC SSIDs can still be discovered.
