Issue description

I get a "The Python interpreter can't be found" error when running pipenv install --system with a python3 but no python.

Demo:

$ docker run $(docker build -q -f Dockerfile.pipenv-2022.8.15 https://github.com/jfly/2022-08-16-pipenv-system-which-issue.git#main)

I'm confident this bug was introduced in f276360, which removed a usage of first(), but broke the "filter None values" behavior that first() gave us.

This fixes pypa#5261.

Before this change, I would get a "The Python interpreter can't be
found" error when running `pipenv install --system` with a python3 but
no python.
