    tests/acceptance: wait() instead of shutdown() where appropriate
    
    When issuing 'reboot' to a VM with the no-reboot option, that VM will
    exit. When then issuing a shutdown command, the cleanup may race.
    
    Add calls to vm.wait() which will gracefully mark the VM as having
    exited. Subsequent vm.shutdown() calls in generic tearDown code will not
    race when called after completion of the call.
