Fix spinach tests

Because of https://gitlab.com/gitlab-org/gitlab-ce/issues/22546 we have false positive spinach tests for a while which cause breaking some of them without us doing nothing. So now when https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/6708 is merged we need to fix spinach tests to have a green build in master

• spinach 2 10 https://gitlab.com/gitlab-org/gitlab-ce/builds/5140873 - fixed by !6916 (merged) and https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/6923 and https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/6932
