[server] Abort orphan scan/delete if known image list is empty
On the off-chance that something goes wron when querying, or the
database got emptied, don't just blindly wipe the whole vmstore. It's
probably smarter to restore a backup first, or if you really mean to
start afresh, just empty the vmstore manually, or just upload one VM and
then use this feature again.
