[BUG] having this plugin enabled breaks Intellij Idea failed test reports

Ok, so this was a weird one to debug...

Simply having the pytest-recording plugin enabled breaks Intellij Idea pytest failed test reports in some specific test cases (here is an example):

a test cassette is being recorded via plain vcrpy syntax or via pytest-recording decorator;
two (or more) network calls are being executed and recorded: the first one succeeds, the second fails and then an error is raised by requests' raise_for_status() method.

Instead of reporting the correct stack trace and main error, Idea reports there has been a failed string comparison involving url paths.

My guess is that pytest-recording breaks something Idea's test runner relies on to generate errors messages, because:

pytest output in the terminal is consistent and correct with or without the plugin installed;
disabling the pytest-recording plugin in Idea ui by adding -p no:recording as additional argument restore the correct error message;
removing the plugin also restore the correct error message.

How to reproduce the issue

Checkout the minimal test repo with git clone https://github.com/CarloDePieri/pytest-recording-idea-issue.

Create a virtualenv and install all dependencies there:

cd pytest-recording-idea-issue
python -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt

IMPORTANT:

this DOES NOT install pytest-recording;
the test we are going to launch DOES NOT use this plugin decorator, but plain vcrpy.

Then:

import the folder into Idea as a new project;
add the created virtualenv as a python sdk for the project;
run the test from the Idea ui: observe that the test fails with the correct error message reporting a 404;
manually install pytest-recording with pip install pytest-recording in the venv;
relaunch the test from the Idea ui: the error message is now completely off track: it reports a difference between expected and actual values '/api/users/23' != '/api/users/2'.

Under the hood

Idea uses this test runner to launch pytest tests and generate the report message. Launching the script directly in the terminal shows indeed the wrong error message when pytest-recording is installed.
