Fix initialization of pg_stat_get_lastscan()
A NULL result should be reported when a stats timestamp is set to 0, but
c037471 missed that, leading to a confusing timestamp value after for
example a DML on a freshly-created relation with no scans done on it
yet.
This impacted the following attributes for two system views:
- pg_stat_all_tables.last_idx_scan
- pg_stat_all_tables.last_seq_scan
- pg_stat_all_indexes.last_idx_scan
