Fix drive.getAudioTitle returning null for no disk

Browse Source 
Historically (and according to the docs) getAudioTitle returned "false"
when the drive was empty (or had invalid media), and "null" when the
disk had no item. This was accidentally changed in a later refactor --
this change fixes that behaviour.
