kirrg001 4265afe580 Moved utils/url.js to UrlService
refs #9178

- we have to take care that we don't end up in circular dependencies
  - e.g. API requires UrlService and UrlService needs to require the API (for requesting data)
- update the references
- we would like to get rid of the utils folder, this is/was the most complicated change
