--use_prepared_statements=0 in ci.yaml is broken

[mjskier]

In init() in driver_test.go, the following 2 lines are commented out

testing.Init()
flag.Parse()

which means any arguments passed to go test in ci.yaml is not taken into consideration.
If you uncomment these 2 lines, you will find that tests with the --use_prepared_statements=0 option fail with the following error in TestBasicArgsWithNil()

driver_test.go:353: Error: [42601] Syntax error at or near ","

@mjskier Thanks for your report! I merged a quick fix for this issue.
