HTTP 500 when listing started jobs in the RQ admin
Sentry Issue: [ARKINDEX-BACKEND-2PW](https://teklia.sentry.io/issues/6603346348/?referrer=gitlab_integration) ``` ValueError: not enough values to unpack (expected 2, got 1) (1 additional frame(s) were not displayed) ... File "django/core/handlers/base.py", line 197, in _get_response response = wrapped_callback(request, *callback_args, **callback_kwargs) File "django/views/decorators/cache.py", line 80, in _view_wrapper response = view_func(request, *args, **kwargs) File "django/contrib/auth/decorators.py", line 59, in _view_wrapper return view_func(request, *args, **kwargs) File "django_rq/views.py", line 227, in started_jobs executions = get_executions(queue, job_ids) File "django_rq/utils.py", line 164, in get_executions job_id, id = key.split(':') ``` When a queue has any job currently running, listing the currently running jobs causes a HTTP 500 because django-rq 3.0.0 does not support RQ ≥2.2
