[PY-53431] Fix setattr(self.current_test_item, _ASSERTION_FAILURE_KEY, (op, left, right)) error

[ben-cutler-datarobot]

Hello, in my PyCharm IDE I frequently get an error:

self = <teamcity.pytest_plugin.EchoTeamCityMessages object at 0x130e3d810>
config = <_pytest.config.Config object at 0x10a15c520>, op = '==', left = 2
right = 0

    def pytest_assertrepr_compare(self, config, op, left, right):
>       setattr(self.current_test_item, _ASSERTION_FAILURE_KEY, (op, left, right))
E       AttributeError: 'NoneType' object has no attribute '_teamcity_assertion_failure'

Because the default value of current_test_item is None:

teamcity-messages/teamcity/pytest_plugin.py

Line 91 in aa8878b

self.current_test_item = None

As do many other people at my company who use pycharm.

We have manually edit the code in the PyCharm environment to comment out the setattr call, then whenever we get a pycharm update we have to do it again. It's a massive hassle, and I'd like to fix this.

Unfortunately, I have no way to test this 😢
