Docker, pipenv en PIPENV_VENV_IN_PROJECT not playing nice

[marcvdijk]

When installing MDStudio using pipenv and PIPENV_VENV_IN_PROJECT=1 followed by building and/or starting docker image for crossbar (using standalone.sh) the following error is logged for the mdstudio_crossbar_1 docker:

When temporary renaming the local .venv virtual environment to venv docker builds and/or starts normally.
