HUE-3756 [editor] Better update of the available queries in the History refresh

If we have a lot of available ones, the number of calls is huge.

How about refactoring it to be a clean 2 loops:

    one for the 'running' ones that checks every 30s
    one for the 'available' ones that checks every 5min

and we start both at the initial notebook page load.
