Throwing SkipTestException doesn't mark test as skipped anymore

[obligaron]

When updating from 0.25.21 to 0.55.23 we discovered that SkipTestException doesn't mark tests as skipped anymore (now are marked as failed).

Sample code:

[Test]
public async Task TestA()
{
    await Task.Yield();
    throw new SkipTestException("i should be skipped");
}
