pytest-subtests is breaking the logs

[PhilipGarnero]

As of today with Pycharm Build #PY-232.10300.41, I an issue with the logs not being parsed properly.
Everything works fine in a regular terminal.
Setting the JB_DISABLE_BUFFERING env var works but isn't ideal.

It is very easy to reproduce so I hope the fix will be easy for you.
In order to reproduce, you need to run unittest fashion tests with the pytest runner and pytest-subtests installed.
Then you need to setup a test class using unittest :

from unittest import TestCase

class TestTeamCityDisplayBug(TestCase):
    def test_display(self):
        for i in range(3):
            with self.subTest(i=i):
                self.assertEqual(True, False)

When you run it you get :

============================= test session starts ==============================

#281 might fix your issue. I only paid attention to the PyCharm GUI, but as far as I understand it is based on the logs.
