failed workflow banner is shown even if only extra tests failed #4
Description
If a test is marked as extra then failing this test will always fail the whole workflow and thus lead to a workflow banner that indicates failure.
This can confuse students who know that they don't need the extra work to get full points (and indeed, the point banner shows that they have NN/NN points).
Failing extra tests should not fail the whole workflow or at least the "passing" banner should be shown if all regular tests passed. See also #3 .
