Merge branch 'fix-ensure_pipeline' into 'ce_upstream'

Fix test for 'pages are deployed'

Fixing this: https://gitlab.com/gitlab-org/gitlab-ee/builds/3686311

The reason is that `Project#ensure_pipeline` switched the order of arguments, but this test is EE-only therefore this change was missed.

See merge request !711
