1. Python version python --version >> 2.7 & 3.5+
2. Test Junkie version pip show test_junkie >> 0.7a4 and prior
3. Platform aka Windows 10 or Linux Mint 18.1 >> All
4. Command used, if running via terminal >> N/A
5. Smallest code snippet that can reproduce the issue and /or description of the issue

from test_junkie.decorators import Suite, test, beforeClass
from tests.junkie_suites.TestListener import TestListener


@Suite(retry=2,
       listener=TestListener,
       priority=2, feature="Store", owner="Mike", parameters=[1, 2])
class NewProductsSuite:

    ATT = 1

    @beforeClass()
    def before_class1(self):
        if NewProductsSuite.ATT == 2:
            raise Exception("Derp")
        NewProductsSuite.ATT += 1

    @test(component="Admin", tags=["store_management"], parameters=[10, 20], parallelized_parameters=True)
    def edit_product(self, parameter, suite_parameter):
        print("edit_product")

    @test(component="Admin", tags=["store_management"])
    def archive_product(self):
        print("archive_product")


if "__main__" == __name__:
    from test_junkie.runner import Runner
    runner = Runner([NewProductsSuite])
    runner.run(test_multithreading_limit=4)

Expected behavior

archive_product should not be marked failed after it has passed initially.

Actual behavior

archive_product gets two metric updates, one is marked success and the other is marked as error due to exception in before class.
