Bug #10288: Fix newly identified issues to make our test suite more robust and faster
Step "a screenshot is saved to the live user's Pictures directory" is fragile
Fails with "No screenshot was created in /home/amnesia/Pictures (Timeout::Error)"
Happened 17 in June, 34 for what 2017 logs we have.
Related test jobs failures are tagged in their description in Jenkins.
That's maybe a resurrection of #8952?
