Setup/teardown is failing when doing automated tests

[singingwolfboy]

This is a bug report about doing setup/teardown for running automated tests with Tartiflette (and tartiflette-aiohttp). It seems that the first test succeeds, but subsequent tests fail. I've created a repository with a minimal reproducible test case, which is here: https://github.com/singingwolfboy/tartiflette-test-bug

• Explain with a simple sentence the expected behavior (above)
• Tartiflette version: 1.4.1
• Python version: 3.10.0
• Executed in docker: Yes
• Dockerfile sample: https://github.com/singingwolfboy/tartiflette-test-bug/blob/main/Dockerfile
• GraphQL Schema & Query: unrelated
• Is it a regression from a previous versions? unknown
• Stack trace: in the README of the repo (click on "Here's an example of the test failure output" to see it)
