When options are provided and follow is more than 1

[sachinraste]

I encountered this issue when I had set the options

test case : gst.gov.in
var opts = {
"server": "whois.registry.in",
"follow": 3,
"verbose": true
}

the first lookup provided the results and did not contain any additional value in match[3]. Due to this , the values from servers.json was used . Incidentally, the value for "in" tld is incorrect.

In some cases match[3] is empty eg. match ["","","",""]

Solution :
index.js -->
if (match[3].trim().length == 0 ){
match[3] = options.server;
options.follow = 1;
}

PS: use dig tld.whois-servers.net CNAME to find the correct whoisServer in case servers.json has an incorrect value.
