Session rename, commit CLI commands not working due to invalid initialization

[jopemachine]

What Operating System(s) are you seeing this problem on?

Linux (x86-64)

Backend.AI version

main

Describe the bug

❯ ./backend.ai session rename 534d186c-f73b-4e1d-b96d-846b51accabc name
✘ BackendAPIError: 404 Not Found
  No such session.
  ➜ Message: Session (id=None) does not exist.

The "Rename" command is not working.
This is because the API should receive session_name, but since the ComputeSession is created via from_session_id, session_name is set to None.

To Reproduce

Use the CLI command.

Expected Behavior

Rename should work

Anything else?

None

This is ultimately related to a missing async attribute population after creating ComputeSession instances using the from_session_id() classmethod.

I have confirmed that the session commit command also causes the same error for the same reason.

❯ ./backend.ai session create python
∙ Session ID 32083c8d-0aa8-4d2a-9cd2-65701e22752a is created and ready.
∙ This session provides the following app services: sshd, ttyd, jupyter, jupyterlab

❯ ./backend.ai session commit 32083c8d-0aa8-4d2a-9cd2-65701e22752a
