bug 917582

-OperatorVariantHelper error when IccHelper.enabled == false should be more descriptive since it is an expected error when running in b2g desktop or fxos simulator.
-Do not throw when IccHelper is undefined, it only indicates that the feature was omitted in the build.
-Fix MockWakeLock object in Contacts.
-Fix GmailConnector Test.
-Fix Settings Test in Contacts.
