Dont save Screenshots automatically

What does this MR do?

Another attempt at fixing https://gitlab.com/gitlab-org/gitlab-ce/issues/58882

Two things could be happening here:

1. When capybara-screenshot attempts to take a screenshot, the session is destroyed by either the runner, or capybara.
2. The space on the runner(s) in question might be filling up tmp/capybara and not able to save the screenshot

Does this MR meet the acceptance criteria?
