Warn when removing all administrators or your own rights


  1. should it be possible to remove all system administrators? no other role can add system administrators so I doubt it should be possible to completely empty that group.

  2. when removing your own access I think you should get a warning beforehand. So logging in as me, and editing the system administrators team, accidentally removing even my own access, it would’ve been nice if octopus said “You are about to remove your own membership in this team and might not have sufficient rights to edit it afterwards. Sure you want to continue?” or something in the lines
