show-action-status command partially broken since 2.9.32

Tested on :
* 2.9.31 (works)

* 2.9.32 (broken)
* 2.9.33 (broken)
* 2.9.34 (broken)

Since Juju 2.9.32 it is not possible to use ```show-action-status``` command without the action id, to get an overview of all actions run or being run on the model.

# From current Snap latest/stable release
ubuntu@maas:~/test_juju$ juju version
2.9.34-ubuntu-amd64
ubuntu@maas:~/test_juju$ juju show-action-status
{}
ERROR task id "" not valid

The only workaround found so far is to download juju 2.9.31 binary to get an ouput.
ubuntu@maas:~/test_juju$ ./juju-2-9-31 version
2.9.31-ubuntu-amd64
ubuntu@maas:~/test_juju$ ./juju-2-9-31 show-action-status
actions:
- action: get-root-ca
  completed at: "2022-09-20 07:14:28"
  id: "2"
  status: completed
  unit: vault/0
...
- action: juju-run
  completed at: "2022-09-20 08:11:20"
  id: "8"
  status: completed
  unit: machine-2-lxd-0

From my testing, it seems to fail starting from Juju 2.9.32 release :
ubuntu@maas:~/test_juju$ ./juju version
2.9.32-ubuntu-amd64
ubuntu@maas:~/test_juju$ ./juju show-action-status
{}
ERROR task id "" not valid
