Follow-up to #2469721: Add functionality to store browser output to BrowserTestBase
Problem/Motivation
PHPStorm doesn't handle custom result printers well - https://youtrack.jetbrains.com/issue/WI-24808 is resolved. Drupal provides a result printer that links to the html output results for functional tests. Let's disable it for the time being.
