/**
* This test checks that an offline cache update scheduled *after* a low device
* storage situation appears is canceled. It basically does:
*
* 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 receive 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.
