tests/settings.py written outside mount

[jacobtylerwalls]

Before, django-docker-box would leave a settings.py under tests/, leaving me with a dirty worktree. That was not so hard to manually clean up every time.

Now, on recent versions of Docker (I'm on 4.55.0), I get the following on the first run:

Error response from daemon: failed to create task for container: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: error during container init: error mounting "/host_mnt/Users/jwalls/django-docker-box/settings.py" to rootfs at "/django/source/tests/settings.py": create mountpoint for /django/source/tests/settings.py mount: mountpoint "/run/host_virtiofs/Users/jwalls/django/tests/settings.py" is outside of rootfs "/var/lib/docker/overlay2/628c5239ecc7925c7c56be8c11dd6f1dad850deb8bedc4019d955efe08bf3443/merged"

And then, once tests/settings.py exists, the second run succeeds.

So I'm now in the habit of just invoking the run twice.
