[BUG] Empty body in HTTP responses dumped with options -svd -vdl

[KGorbakon]

Is there an existing issue for this?

• I have searched the existing issues.

Current Behavior

HTTP resposnse body is not visible after using -svd and -vdl options, There are only response headers and tabulation space after them.

Expected Behavior

Responses' body should be visible in variable dump.

Steps To Reproduce

1. Create template:

javascript:
  - code: |
      let m = require('nuclei/net');
      let address=Host+':'+Port;
      let conn;
      conn = m.OpenTLS('tcp', address)
      conn.Send('GET / HTTP/1.1\r\nHost:'+Host+'\r\n\r\n');
      conn.RecvString();

    args:
      Host: "{{Host}}"
      Port: "443"

    matchers:
      - type: dsl
        dsl:
          - 'contains(response, "Example Domain")'

2. Run nuclei:
   nuclei -t .\template.yaml -debug -svd -vdl 10000 -u https://example.com

Relevant log output

PS C:\path\to\template> nuclei -t .\test.yaml -debug -svd -vdl 10000 -u https://example.com
