Modify tests to make more platform agnostic

Browse Source 
When testing on Windows these tests were returning differences
because of floating point (sql_query_results_*) differences and
because the cost was trivially higher (insert_single). Here we
remove the costs since it was not relevant to the regressions we
want to detect. Further we truncate the floating point averages
to 8 decimal places; enough to see significant differences.
