Bug 1086205 - Add an abstract class for status bar icons for marionette ...

...tests
If we're dispatching a geolocation-status event I don't think there should be much of a delay here? In any case, I would recommend trying to solve problems like this without the delay if possible. Mocking out the necessary interfaces, or triggering events is preferred. 

I think we are ok here, but Guillaume please correct me if I'm wrong.
