* This test checks that an offline cache update scheduled *after* a low device

* 1. Notifies to the offline cache update service about a fake
* low device storage situation.
* 2. Schedules an update and observes for its notifications.
* 3. We are supposed to recieve an error event notifying about the cancelation
* of the update because of the low storage situation.
* 4. Notifies to the offline cache update service that we've recovered from
* the low storage situation.
