#2125 Deleting REFerenced entries should not be possible

[G.Shum]

Just for the fun of it, I'd created two entries "test 1" and "test 2". In the username of the "test 2"-entry I've inputted "{REF:U@U:test 1}". Much to my surprise it was posible to delete the "test 1"-entry without any warning.
Perhaps this is worth solving.

Thank you for a great piece of software.
Kind regards.
