AutoTest: WARN state prevails over specific test state

Problem: Currently in the nested output of Test Results, whenever the outcome of the test is not FAIL and there is a WARN at some point, the test will be yellow whether it is a PASS, SKIP and possibly some other states.

This makes it impossible to know at a first glance whether a test passed, was skipped etc without expanding its node.

Proposed fix: either treat the other cases like FAIL, which prevails over WARN, or find a way to show both WARN and the outcome in the test overview, maybe showing the yellow dot of the WARN and a second outcome colored dot, next to eachother
