Work on accomodating missing Angular/Node dependencies into the NPM scoring module

[rootAvish]

Issue Overview

Currently for a lot of the angular repositories we are not able to see insights because the dependencies in them are not covered in the recommender model and there are too many unknown packages.

Expected Behaviour

We should see insights for more frontend javascript stacks.

Current Behaviour

Companion insights count is 0 for some frontend stacks (specifically ones using a lot of ngx-* dependencies).

Steps To Reproduce

1. Run stack analysis for one of the following:

   • https://github.com/socketio/socket.io
   • https://github.com/fabric8-analytics/fabric8-analytics-dependency-editor
