Bug 1053477 - [B2G][OTA][Facebook] Facebook sync settings not preserved ...

...performing OTA from 2.0 to 2.1 in Contacts app
Because the default stub is created in the setup function, and I have to restore it before I make a stub again. Then I don't restore it because it's restored in the teardown. But I think that since this is a bit confusing, I'll make the stub and restore for the lazy loader in every test.
