launcher: fix creation of snap2

Browse source 
When snap1 doesn't exist, `lxc-snapshot` will create a snapshot named
`snap1` (instead of `snap2`). In this case we need to rename snap1 into
snap2.

However the condition check is wrong: after creating the snapshot,
`snap1` will *always* exist – even if it didn't before. Thus the
renaming never happens.

Fix the issue by detecting the absence of snap2 (rather than snap1).
