textclient: don't prompt to change internet email addresses when deleting a user

The 'edit user' and 'delete user' workflows run through the same function since
the process of deleting a user simply edits them and changes their access level
to 0.  Add a check for cmd==25 (edit user) before asking the user if they want
to change the email addresses.
