Redmine

As Jan wrote in #9226, beginners often get confused after creating a new issue status that they cannot find the newly added status in the Status drop-down. This is because they haven't learned that they should associate statuses to trackers by configuring workflows.

I think it is helpful for them if Redmine shows a proper warning when no tracker uses the status in its workflows. The warning will give them a good hint about the fact that they should configure workflows to uses the issue status.
