Use infinite endpoint for snapshot interval in single time series URL.

The URL that refers to a single time series now specifies an
infinite enpoint for the second snapshot (by specifying an
invalid SHA-1). Reloading the page is then guaranteed to show
the latest available results, This is likely to be more useful
in practice.
