Pass 'top' to remove_rule so that rule matching succeeds

When deleting a vpn-site-connection, deleting the nat rule would
fail because it was created with top=True, but top defaults to
'false' in remove_rule and was not being passed. This caused the
rule matching to fail and the rule to not be deleted.
