cleanup: delete VM before deleting the machine's dir

trying to delete the machine's dir without first deleting the hyper-v VM
causes error, since the existing VM will still be using the files inside
the machine's dir

this separates out the check deleting the VM from the list of hyperv
checks, and adds it to the list of all checks after the generic cleanup
checks to make it run before deleting the machine's dir

this fixes #3503
