Cannot empty a group

[sknolin]

Version is 1.1.2 and puppet 6 (latest)

There are cases where you want a group but need no members defined, for example when they have the group as their primary GID.

For example, a group "mygroup" where I put root in it, then try to remove it so it's empty I get this notice:
Group[mygroup]/members: members changed root to (corrective)

And no change, so it runs every time.
