client/tests: add checks to "test-client.py"

- test for "-order" option with `nmcli connection show`.

- test for order of activated devices. Optimally, the devices
  should be in activating vs. activated state. I fail to do that,
  the mock implementation is cumbersome to use. It still seems useful
  to have this (maybe it could be improved).
