Gitlab project onboarding is failing on Gitlab.com

Description

Our Gitlab project onboarding feature started to fail recently due to Gitlab new release. A regression has been introduced in the projects web service pagination, which our integration relies on.

From a user perspective, the issue leads to the following error when reaching the personal access token page for Gitlab or when trying to import a project from Gitlab:

Remediation 

Two bug tickets have been created on Gitlab.com:

1. https://gitlab.com/gitlab-org/gitlab/-/issues/335377#note_621097393
2. https://gitlab.com/gitlab-org/gitlab/-/issues/334667

While we wait for Gitlab to fix their bug, the issue could be completely avoided on our side. We should simply remove pagination information from our calls to the web service when it isn't necessary.
