-sn flag (host discovery only) no longer works

[Jackrin]

Naabu version:

v2.3.3

Current Behavior:

The -sn flag no longer works, instead a port scan is still executed on the hosts.

With just -sn flag:

naabu -sn -silent -host 104.17.214.56,92.123.101.66,2.18.254.131
104.17.214.56:8080
104.17.214.56:8443
2.18.254.131:80
92.123.101.66:443
2.18.254.131:443
92.123.101.66:80
104.17.214.56:443
104.17.214.56:80

With -sn and -wn, I tried just in case:

naabu -sn -wn -host 104.17.214.56,92.123.101.66,2.18.254.131
104.17.214.56:8443
104.17.214.56:443
104.17.214.56:80
104.17.214.56:8080
2.18.254.131:443
92.123.101.66:80
2.18.254.131:80
92.123.101.66:443

Expected Behavior:

On v.2.3.2:

naabu -sn -host 104.17.214.56,92.123.101.66,2.18.254.131        
2.18.254.131
92.123.101.66
104.17.214.56

Steps To Reproduce:

Run naabu v2.3.3, with -sn flag set.
