Create top-level group with non gitlab-qa user

What does this MR do and why?

Address issue - #350322 (closed)

Test groups created in fulfillment section cannot be removed via API calls, due to being linked to paid subscriptions. Test data is piling up on staging for gitlab-qa user.

This MR changes user login order in test before block, so that the test group is created by test user instead of gitlab-qa user.
