Skip transaction check for seeding burndown charts

Closes gitlab-development-kit#351

See merge request gitlab-org/gitlab-ee!5686

The seed-fu gem wraps all seeds in a transaction:
https://github.com/mbleigh/seed-fu/blob/34c054c914858c3d7685f83d16dea5c0e2114561/lib/seed-fu/runner.rb#L35.
We can skip the Sidekiq transaction check for seeding test fixtures.

Closes https://gitlab.com/gitlab-org/gitlab-development-kit/issues/351

An LDAP sign-in request results in a different request parameter than
a standard GitLab sign-in. Since Warden doesn't pass us the user that
was blocked, we first search for a `username` in the request parameters
and then look for `user.login`.
