[Storage][Clone vm from snapshot] Clone VM fails if the source disk was moved to another storage domain. This happens because the information about domains and disks should be taken from the DB and not from the OVF file.
Scenario:
1.Create VM with one or more disks.
2.Make a snapshot.
3.Go to the disks tab and move one of vm's disks to another storage domain.
4.Come back to VM's snapshots tab and try to clone VM from snapshot.
The operation will fail. GUI will stuck on "Clone VM from snapshot" dialog.

As explained at Comment #1 (I reviewed the code with Leonid when he opened the bug) -
The source diskImage is taken from the OVF that is stored per snapshot.
This is wrong - it should be taken from DB, to reflect any change that might have occurred (i.e - storage domain it resides on) after snapshot was created.
