Refactors the getStarred function, refactors its tests.

Browse source 
getStarred queries the Subsonic server and caches the request. It handles both GET and JSONP. It returns meaningful messages when there is a problem and distinguishes between HTTP errors and Subsonic errors.
Those messages are meant to be displayed by the controller using the notifications.

The tests are refactored too : most of what is common is at the top describe to keep the tests lean. Tests for error conditions have been added.
