Prometheus' /series end-point returns an empty array no matter what: if there were results or not. We need to follow the same principle in Thanos as well because our users depend on it. The same fix has been applied like here: https://github.com/prometheus/prometheus/blob/fef150f1b5e48652ec6779e2129ae9a0cf13db8a/web/api/v1/api.go#L506 Tests have been updated to account for this difference and plus one test has been added just for this case. Closes thanos-io#1325.
