Thread: pgsql: pgstat: set timestamps of fixed-numbered stats after a crash.

pgstat: set timestamps of fixed-numbered stats after a crash.

When not loading stats at startup (i.e. pgstat_discard_stats() getting
called), reset timestamps of fixed numbered stats would be left at
0. Oversight in 5891c7a8ed8.

Instead use pgstat_reset_after_failure() and add tests verifying that
fixed-numbered reset timestamps are set appropriately.
