Description of problem:

We create a VM,
Create VirtualMachineSnapshot snapshot-1, 
Write to VM,
Create VirtualMachineSnapshot snapshot-2,
Write to VM
Create VirtualMachineSnapshot snapshot-3,
Restore snapshot-3, delete the VirtualMachineRestore object 
Restore snapshot-2, delete the VirtualMachineRestore object 
Restore snapshot-1, delete the VirtualMachineRestore object 
Delete VirtualMachineSnapshot snapshot-1, 
Delete VirtualMachineSnapshot snapshot-2, 
Delete VirtualMachineSnapshot snapshot-3, 
Delete VM

Result: 
Two VolumeSnapshots are not cleanedup, we can't delete them, but VirtualMachineSnapshots was deleted succesfully.
Two VolumeSnapshotContents are not cleanedup, and we can't delete them, but VirtualMachineSnapshotContent was deleted succesfully.

Version-Release number of selected component (if applicable):

4.15

How reproducible:

Always
