Simplify redundant current_database() subqueries in stats.sql regression test

Previously the stats.sql regression test used conditions like
"datname = (SELECT current_database())" to check the current database name.

The subquery is unnecessary, so this commit simplifies these expressions to
"datname = current_database()".
