Code review comment for lp://staging/~phablet-team/network-manager/lp1445080

Re-tested mako (rc/ubuntu #1) with the new version of network-manager (15.1.4) uploaded to silo 20.

Re-ran all of the tests from:

https://wiki.ubuntu.com/Process/Merges/TestPlans/network-manager

...and made sure to repeat the boot, flight-mode and set-radio tech cases a minimum of five times each.
