Fixing and updating unit and integration tests

• Unit tests and mock data have been updated by adding all the new fields we added while working recently on new features
• New unit tests cases have been added to cover new functionality
• Integration tests have been fixed and they are working right now
• New integration tests cases have been added to cover new functionality
• Validator has been updated to consider all new fields we have added to the request body when registering/updating instruments
• Some changes have been done at controller/service layer to fail properly when there is no data while getting a non-existent instrument. Some other fixes have been done to improve the error management
• npm run lint:fix have been executed to fix some related errors (anyway there are still a few pending)
• Added a new Makefile goal (make all-test) to rebuild automatically the test environment and run all tests (unit + integration)
