Delete admin account

Hi,

When you delete the admin account via the client, you can delete it while logged in. Maybe it’s a good idea to force a logout when that happens, and also warn if you are deleting the last account on the system (so you could not lock yourself out).

NCSX is never locked out. it creates its own temporary admin account when being started so worse case use NCSx to recreate a new account which can be used from the client.
