[mako] test-sims-offline fails due to CallVolume 'Muted' property

[Tony Espy]

When mako is in flight-mode, and the test case 'test-sims-offline' is run, it fails an assertion due to the CallVolume 'Muted' property being inverse from other devices ( it's 0, when it should be 1 ).

This bug was found while testing a silo containing lxc-android-config, nuntium, and ofono for the touch OTA5 milestone. Note, a newer version of network-manager ( 4ubuntu15.1.4 ) was also installed when this bug was discovered.
