Fixes BUG-46140: parameters can be passed to npn test and npm coverage
Now all parameters are forwarded from run-tests to jest.
Both positional parameters and named parameters are supported. Remember that in order to pass named parameters to npm test they must be included after -- 
- npm test (executes all tests)
- npm test modules/org.openbravo.client.application/web-test/ob-utilities-date.test.js (executes single test)
- npm coverage modules/org.openbravo.client.application/web-test/ob-utilities-date.test.js (executes coverage for single test)
