Title: Fix live snapshots

The live snapshots method uses 'extract_snapshots' which we had
an older version of. The latest H4 tarball shows that we do not
pass the name, but the dirty merge we did for the rbd clone did.
As such, when we were doing live snaps, we'd raise the error
TypeError: extract_snapshot() takes exactly 5 arguments (4 given)
as it was expecting the name to be passed.
