Met this issue when test watauga4.0

Scenario
Launch checkbox with checkbox-cli
When run reboot/power off test and re-launch checkbox, no matter choose which of following options, session can not continue properly.
What do you want to do with that job?
  s => skip that job
  p => mark it as passed and continue
  f => mark it as failed and continue
  r => run it again
