CLOUDSTACK-9676 Start instance fails after reverting to a VM snapshot, when there are child VM snapshots

Browse Source 
Issue
====
Start instance fails after reverting to a VM snapshot, when there is 1 or more child VM snapshots in the snapshot tree of the VM.
Per the code that detects the presence of a snapshot, we are checking for only current snapshot instead of checking presence of any snapshot in the snapshot tree.
The failure to detect all snapshots means ACP reconfigures the VM in wrong way assuming there are no snapshots for the VM.
This results in start failure.

Fix
===
Ensure correct detection of VM snapshots in the VM snapshot tree
