Charge threshold doesn't work with suspend-then-hibernate

Expected Behavior

After resuming from suspend-then-hibernate, if battery level is above charge threshold (80), it shouldn't be charging.

Actual Behavior

The battery is charging despite that battery level is above threshold (80) after resuming from suspend-then-hibernate.
bat -t correctly shows the threshold I configured. Manually setting charge threshold again makes it work properly.

Steps to reproduce

  1. Set threshold and persist. sudo bat -t 80 sudo bat -p.
  2. Set appropriate HibernateDelaySec (like 20 for testing) in /etc/systemd/sleep.conf.
  3. Charge the battery until it meets the threshold. Check that the battery is not charging with bat -s.
  4. sudo systemctl suspend-then-hibernate and wait for it to enter hibernate mode.
  5. Resume from hibernate. Check battery status with bat -s and it says it's charging.
  6. Run sudo bat -t 80 then check battery status. This time the threshold works and battery isn't charging.

Additional Notes

With both suspend and hibernate the threshold works properly.
I tried both 0.8 and 0.8.1, neither works.

Thank you for filing the issue. Here's a proposed fix. Let me know if works and confirm that the version is 0.8.2-alpha before running it.

After using the new version to do sudo bat -t 80 and sudo bat -p then reboot the system, it seems to work !
