Title: User friendly response if deletion of a build fails

If a build is deleted shortly after stopping, sometime the deletion fails and users see page with stack trace (probably due to longer clean up, after a few seconds max 1 minute users can delete it without problems). It will better to show information that deletion fails and retry button.
