Bug: JSON output is not valid when the target is not a webserver

[nodauf]

Expected behavior

The json report should be valid.

Actual behavior

When nikto is run on a port where there is no webserver the output is

{"id": "000029","OSVDB": "0","url":"/","msg":"No web server found on localhost:8080"}}

At the end there too many is a }. One came from report_item and the other from report_close

Steps to reproduce

1. Start netcat : nc -lvp 8080
2. Run nikto: nikto -host http://localhost:8080 -ask no -o /tmp/out.json

rearranged things so the json is now valid if the host can't be connected to, as well as add the host meta information.

{"host":"localhost","ip":"127.0.0.1","port":"22","banner":"","vulnerabilities":[{"id": "000029","method":"TCP","url":"","msg":"Unable to connect to localhost:22."}]}
