1. because we didn't have this behavior till now.
2. because for templates you may want to preserve the uuid to move over 
VMs/chains using it.
3. because import keeping uuid's allows to handle snapshot chains and 
re-use of template which does not require changing the actual images, 
still pointing to the low level actual file/chains (can also be fixed by 
separating internal uuid's and disks/snapshots uuids, but much more work)
