This commit fixes the original #11027 fix, which assumed that the hyper-v provider just wasn't properly getting a VM id when it listed snapshots. In reality, it was just that if you invoke the `with_target_vm` method with no arguments, it runs on the entire environment. This meant that the capability snapshot_list attempted to be invoked on machines that didn't exist yet, which is the original cause for why the list_snapshot method did not recieve a vm ID. This commit fixes that by simply skipping the machine if it does not yet exist.
