Fix issue with deactivated offers getting published after editing

- Add check if editedOpenOffer is not deactivated to avoid republishing
- Use errorMessageHandler instead of IllegalStateException. We can discuss if you would prefer that style but so far we did not throw exceptions to the UI but rather use error handlers.
- Small cleanups
