Unit tests and linting in CI/CD [DEVOPS-408]

[soar]

https://jibrelnetwork.atlassian.net/browse/DEVOPS-408

We have some problems:

• Jest can't execute tests
• xml report generated by Jest has no valid information
• coverage report doesn't contain xml in Junit format
• linters don't generate Junit reports, I think we should add these modules:
  • https://github.com/jcgertig/eslint-junit
  • https://www.npmjs.com/package/stylelint-junit-formatter

Please, fix these issues and add them into this branch/PR. You can find build logs here:
