Bug description:
  While trying to reproduce another bug related with the last seen value
  from the access points, I noticed that network manager is never really
  scanning for new access points on my desktop, not even when not

  $ sudo nmcli g logging level debug domains wifi_scan

  Then powered an access point, but was never really able to see it.
  From syslog, noticed that there is never really a scan, which explains
  why the ap never goes away and why it is not able to find it in the
  first place.

  If I force a scan via cmdline it works as expected (and I noticed a
  scan also happens when changing connections).

  Was also able to reproduce this issue on mako, with the following image:
  phablet@ubuntu-phablet:~$ system-image-cli -i
  current build number: 173
  device name: mako
  channel: ubuntu-touch/devel-proposed
  alias: ubuntu-touch/vivid-proposed
  last update: 2015-04-16 14:58:58
  version version: 173
  version ubuntu: 20150416
  version device: 20150210
  version custom: 20150416

  In the mako case, I booted with a known connection in place, it
  connected successfully but it never really scans for other access
  points. Scan works fine after disconnecting though.
