Groups with 0 Owners are not possible

User stories

As a User, I want Groups with 0 Owners to be not possible in order to not crash if they have none

Acceptance Criteria

• Given a Group with exactly one owner that is not a system Group, then there is no Button for that owner to demote themselves or leave the group

I'm not really sure why this should be a feature. We currently have the option for groups that don't have a specific owner, so called "system groups". F.e. the default hpi group is working as intendend.

Is this ticket about these groups, or should users be able to create a group that does not have an owner?

If that is working as intended and you can choose these Groups When creating an Item as Groups with permissions then you could also implement that the last owner cant leave the group or demote himself because either way we dont want broken groups. Either by just saying they are not broken (the original idea of this issue) or by forcing group owners to stay in their group and not destroying it in the first place

I think it's reasonable to implement it like this:

• Given a Group with exactly one owner that is not a system Group
• Then there is no Button for that owner to demote themself or leave the group

And I don't change the underlying Model, e.g. groups are only valid if they are a System Group or they have at least one owner.

or is this something that's already being implemented by a different Team?
