This reverts commit a0fd3dc0fe5913335bfe294b6470e46836e97287 as that fix
does not work since the issue it aimed to fix can still happen when
running cypress tests in parallel on Jenkins.

See https://jenkins.softwareheritage.org/blue/organizations/jenkins/DWAPPS%2Ftests-on-diff/detail/tests-on-diff/2093/pipeline/123

I guess I will have to report that race condition issue to cypress then.
