pytest-xdist crashes tests

[mfreibergs]

Running tests with pytest-xdist in parallel doesn't correctly clean up the test-results folder and crashes the tests. Don't know if this can be fixed from playwright-pytest or pytest-xdist instead

# conftest.py
import shutil
import os

output_dir = "test-results"

def pytest_configure():
    if os.path.exists(output_dir):
        shutil.rmtree(output_dir)

Adding this fixes the current problem. There probably is a better solution.

Should be fixed by #97
