run NPM before build_py

[manics]

The npm ... steps weren't being run for all targets, which means it's possible to install this package without having first run npm to build the JS assets. This might or might not fix it...

Testing

Before every test you must reset everything to a clean state:

pip uninstall omero-parade
git clean -dxf

Test cases:

python setup.py sdist
pip install dist/<file>

python setup.py install

python setup.py bdist
pip install dist/<file>

python setup.py bdist_wheel
pip install dist/<file>

pip install .

I haven't tested this properly, but find indicates the js assets are installed:

$ find /venv/lib/python3.6/site-packages/omero_parade* -name \*js\*
/venv/lib/python3.6/site-packages/omero_parade/static/omero_parade/js
/venv/lib/python3.6/site-packages/omero_parade/static/omero_parade/js/bundle.js.map
/venv/lib/python3.6/site-packages/omero_parade/static/omero_parade/js/bundle.js
/venv/lib/python3.6/site-packages/omero_parade/templates/omero_parade/init.js.html
