Changing the state machine so that RESTORING is not a substate of OFFLINE:NORMAL, but instead of OFFLINE. While a transition from OFFLINE:NORMAL:RESTORING to ONLINE was possible (which was wrong), it will not be possible to transition from OFFLINE:RESTORING to ONLINE.

The proper sequance of events is: OFFLINE:NORMAL --restore--> OFFLINE:RESTORING --restore_complete--> OFFLINE:NORMAL
