[TASK] Make failing acceptance tests after image update run again

The agent update introduced a higher chromedriver version that
caused several acceptance tests to fail. Adjusting wait states
brings them back to green.

The bamboo plan update now uses a php.ini without xdebug and
simplifies the unit test runs in this area, too.

And we need a patch for typo3/testing-framework version 3.4.2:
composer update typo3/testing-framework
