HACK: Render again results for minimal and internal images on <2022 reports

The recent changes in the testcases caused the results for minimal and internal images to ber marked N/A on older releases like v2020 and v2020, due to the app not really supporting diverging releases since it only loads the testcase definitions from the apertis-test-cases HEAD.

To work around the issue, add some hacks until diverging releases are properly supported, see https://phabricator.apertis.org/T8245.

This also reverts commit 86bf12d6 "Update test screenshot" which actually caught the issue but was mistakenly interpreted as the desired outcome.
