app/vmselect: set proper timestamp for cached instant responses (#5723)
* app/vmselect: set proper timestamp for cached instant responses

The change updates `getSumInstantValues` to prefer timestamp
from the most recent results. Before, timestamp from cached series
was used.

The old behavior had negative impact on recording rules as they
were getting responses with shifted timestamps in past.
Subsequent recording or alerting rules fetching results of these
recording rules could get no result due to staleness interval.
