[pbs-devel] [PATCH proxmox-backup] http client: suppress "storing login ticket"-error when not using a TTY

[Fiona Ebner <f.ebner@proxmox.com>]

as a stop-gap measure. Otherwise, task logs for PVE backups started
via non-CLI will have the message
> storing login ticket failed: $XDG_RUNTIME_DIR must be set
show up when running a proxmox-backup-client command (e.g. setting
notes and when uploading the log). This is confusing to users[0].
