cli: fix crash on autocompletion

Browse source 
@connections is NULL when doing autocompletion. Fixes the following:

 $ nmcli --complete-args con monitor ""
  help
  id
  uuid
  path
  filename
  ...
  Segmentation fault (core dumped)

Fixes: 4b3297271e ('cli: rework connection handling for multiple results')
