Don't hide the last ban in the list on the CLI ban.list output

The ban.list output would hide the very last ban on the list unless
the lurker debug flag was set. This hides useful debugging information
(how many objects are stuck on the last ban), without giving any
apparent benefit. Remove the hide code.
