Parallel mode disables usedevelop

Instead it will install an sdist.

Reproducing example:

ionel@bionic:/tmp$ cat tox.ini
[tox]
envlist = py36-{a,b}

[toxenv]
usedevelop = true

ionel@bionic:/tmp$ cat setup.py
from setuptools import setup

setup(name='foobar')

I have found this problem while trying to figure out how to skip wheel building when not really necessary for my tox-wheel plugin. I have this feeling that whatever the fix will be it will break my plugin so lets discuss first I guess?

[atugushev]

@ionelmc looks like rename [toxenv] to [testenv] fixes the issue. See:

$ cat tox.ini
[tox]
envlist = py36-{a,b}

[testenv]
usedevelop = true

Coverage showing the paths as .tox/coverage/lib/python3.10/site-packages/check_python_versions/ indicates that usedevelop = true in my tox.ini was ignored.

Running tox -e covergage afterwards showed the correct 100% coverage with the paths in the coverage report showing src/check_python_versions/.

Since life is short and sporadic errors like this are annoying I modified check-python-versions to no longer use usedevelop in the next commit, but I thought you might want to know that the bug is not fixed yet.
