Properly report test failures

Assume the following test file `test_it.py`:
```python
import pytest

@pytest.fixture
def foo():
    return True

@pytest.fixture(scope='session')
def bar(foo):
    return False

def test_it(bar):
    assert bar is False
```

When running pytest, it will error out because of the fixture scopes.
Previously `pytest_reportportal` would wrongly mark the test as skipped,
with this change it correctly marks it as failed.

Fixes #44
