Demo details are incorrect

[projx]

Hi

It seems the path details shown on https://github.com/viewflow/viewflow/tree/master/demo are incorrect, it shows:

tox loaddata tests/helloworld/fixtures/default_data.json
tox loaddata tests/shipment/fixtures/default_data.json

But these files appear incorrect, should the test/ be replaced with demo/?

Thanks fixed
