Raising error in unittest's setUpClass causes autograder breaking exception

[alexadkins]

Describe the bug
Raising an Assertion Error in unittest's setUpClass method causes exception in jsontestrunner's getLeaderboardData

To Reproduce

import unittest
from gradescope_utils.autograder_utils.decorators import (
    weight,
    number,
    leaderboard,
)

class TestAutograder(unittest.TestCase):
    @classmethod
    def setUpClass(cls) -> None:
        raise AssertionError("compile for all tests failed")
        return super().setUpClass()
    
    @number(1.1)
    @weight(1)
    def test_01(self):
        "Test 01"
        pass

Expected behavior
Raised error would have populated results.json for all test cases of that class.

Instead, received following error:

The autograder produced the following output:

Traceback (most recent call last):
  File "/usr/lib/python3.10/unittest/suite.py", line 166, in _handleClassSetUp
    setUpClass()
  File "/autograder/source/tests/test.py", line 14, in setUpClass
    raise AssertionError("compile for all tests failed")
AssertionError: compile for all tests failed

During handling of the above exception, another exception occurred:

I fixed this issue in my fork (see #38).

GS doesn't seem to be responsive here for some goofy reason, but if you want to use my fork with your autograder you can add
git+https://github.com/gregbell26/gradescope-utils to your requirements.txt instead of the official package.

Im also working on a complete rewrite of this package that will support the new features that the GS team has added to the platform.

I now have an official package that fixes this.
