npm `test` and `test-container` should use the same spec files

[muxator]

13d9e86 (part of #3677) introduced a useful feature (running a simplified version of backend tests in CI via Docker), but in doing so copied & modified & pasted two files. See #3677 (comment):

• backend/loadSettings.js container/loadSettings.js
• backend/specs/api/pad.js container/specs/api/pad.js

This was very useful to get the feature out, but now it would be better to unify the spec files.

A possible idea could be pass some parameters at runtime, so that npm test and npm test-container end up calling the same script with just different command line parameters.

Any idea on how to achieve this?

npm run test now runs on travis when the backend tests run
