What is the current behavior?

Exception in a fixture will break the test as expected but step corresponding to that fixture will be shown in green (little arrow to colapse or circle).

If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem

Could be just an exception inside feature:

@pytest.fixture
def fixture1():
    raise Exception

What is the expected behavior?

This symbol (arrow or circle) corresponding to the fixture should be also yellow

What is the motivation / use case for changing the behavior?

This is needed because we need to have an indication of what fixture has broken the test.
See screenshot below - all steps are shown in green although test was broken.

Please tell us about your environment:

• Allure version: 2.1.0
• Test framework: pytest@3.0
• Allure adaptor: allure-pytest@2.0.0b1
