Description of the issue:

During computations of a task (20 frames, 40 subtasks) checking list of subtasks in cli appeared

Error: WampError(WampError { code: Canceled, message: "callee disconnected from in-flight request", extra: {} })

When checking some of the subtasks were timed out, task was still computing. Reproduced it several times when this task was being computed. Later on, after the task was finishing listing subtasks for this task worked normally. In next tasks it was also possible to check list of subtasks from cli.

Actual result:

It was not possible to check subtasks in a task

Steps To Reproduce

Short description of steps to reproduce the behavior:
e.g.

1. Launch the app 0.23.0 version
2. Start a task, DiscBoyBlender frames 40-59, subtasks 40, task timeout 3h, subtask timeout 20 min, res and samples from file, bid 0.1, concent off
3. Wait for computations of a task
4. Task should be still computing, several subtasks finished and several timed out
5. Type in terminal `golemcli tasks subtasks list <task_id>
