Describe the bug:
While trying to navigate to "Overview" of the elasticsearch's monitoring, I get a blank page with the error message mentioned in the bug's title.

Steps to reproduce:

1. Open Monitoring -> Elasticsearch -> Indicies
2. I've time values set as following: refresh interval: 10s, clock: last 1 hour
3. Click open in new tab on "Overview"
4. A new tab opens with the error message "Monitoring: Error 404 Not Found: The cluster [undefined] was not found within the selected time range."

The error appears only if you open overview in new tab/window. It won't happen if you open Overview in the same tab where you view Indicies.

Expected behavior:

The problem is, undefined is not a valid Cluster UUID. The browser got into a state where it doesn't have the cluster_uuid in the globalState.

The globalState is passed around from page to page through links, as it is part of the URL. For example: ?_g=(cluster_uuid:H6N-buS3TU-UpsuETW3VXA)

However, the carryover doesn't work if you try to open a link in a new tab, or do something to navigate to a deep view without a cluster_uuid.

The workaround is to reset the invalid browser state by clicking the Monitoring icon in the Kibana sidebar and starting again from the top. If a little "toaster" window pops up at the bottom with a "Retry" button, clicking Retry will do the same thing.
