fix: stateMachine is not updating after account logout

After user logged out from the account, stateMachine doesn't move to
idle state, but the jobs are canceled. Which create some issue until
user reboot the device.

example, if the state IS `PERIODIC_SCAN`, & account logged-out,
FullScanWorker will be stopped, but state won't update. So if user
re-login, the FullScannWorker won't run again, until user reboot device.
