[PATCH proxmox-backup] fix #6251: api: Remove running tasks from errors output

[Jonas Theisen <j.theisen@proxmox.com>]

Currently running tasks are returned by the PBS API in the query
for errored tasks.
This patch adds an additional condition to filter out running tasks
when queried for errored tasks.
