As shaped, two DROP ROLE queries included in "user_activity" were showing in the reports for "wal". The intention is to keep each test isolated and independent, so this is incorrect. This commit adds some calls to pg_stat_statements_reset() to clean up the statistics once each test finishes, so as there are no risks of overlap in the reports for individial scenarios. The addition in "user_activity" fixes the output of "wal". The new resets done in "level_tracking" and "utility" are added for consistency with the rest, though they do not affect the stats generated in the other tests. Oversight in d0028e3.

The PostgreSQL contrib tree
---------------------------
This subtree contains porting tools, analysis utilities, and plug-in
features that are not part of the core PostgreSQL system, mainly
because they address a limited audience or are too experimental to be
part of the main source tree. This does not preclude their
usefulness.
User documentation for each module appears in the main SGML
documentation.
When building from the source distribution, these modules are not
built automatically, unless you build the "world" target. You can
also build and install them all by running "make all" and "make
install" in this directory; or to build and install just one selected
module, do the same in that module's subdirectory.
Some directories supply new user-defined functions, operators, or
types. To make use of one of these modules, after you have installed
the code you need to register the new SQL objects in the database
system by executing a CREATE EXTENSION command. In a fresh database,
you can simply do
CREATE EXTENSION module_name;
See the PostgreSQL documentation for more information about this
procedure.
