Add NOT NULL checking of pg_stat_statements_reset() in tests

Browse Source 
This is preliminary patch.  It adds NOT NULL checking for the result of
pg_stat_statements_reset() function. It is needed for upcoming patch
"Track statement entry timestamp" that will change the result type of
this function to the timestamp of a reset performed.
